The party retires to their rooms, Giles taking the room with Zefla, and Burr and Soren sleeping in the other.  It isn't long before the sounds of footsteps and creaking boards in the Blue Water Inn fade into silence and the four of you find sleep, safe from the terrors of the night.

You have reached Level Three.

Soren:

The occupants of both rooms are awakened with short, sharp knocks on the doors.  In the hall, Urwin Martikov's voice can be heard softly.  "Good Morning.  I had offered to Miss Zefla to visit with you all this morning and answer some of your questions about Vallaki.  May I come in?"

(Sweet, level 3!)

Zefla rubs the sleep from her eyes as she hears the knock at the door.  She looks over at Giles and wonders if it is Soren and Burr, wanting to get moving already.  Sighing heavily, she's about to get out of bed when she hears the voice on the other side.  

Mood changing, she hops off the bed and opens the door widely, "Sure!  C'mon in!"

Giles arises slowly, strapping back on his armor and feeling… different.  He says “Who’s there?” with a tint of suspicion in his voice, looking to meet Zefla’s eyes to see if she’s worried, but apparently not.  He finishes the last buckle and strap and his hand rests on his dagger.  

If Burr's eyes have opened, he would see Soren sit bolt upright in bed with a strangled yell, eyes bloodshot and skin pale as an aspen.

Following his audible shout, the druid's eyes dart wildly, his mouth half open in the rictus of a silent scream.  He reaches deep within himself for Silvanus' wild strength.  When the winter blizzards dull the senses or the summer heat kills the sheltering trees.  When the floods cover all the nurturing earth or pestilence stalks prey and predator alike, there is strength.  The Bear remains strong and resilient.  Resourceful.  The Bear Survives.

Soren reaches frantically for the strength of his Spirit Totem animal, feeling the new power and magic Silvanus has granted him as he does.  There is a distant, deep snuffling sound, as if from a large mammal, injured but unbowed.  He fights desperately to cling to this ursine strength.

Bear Spirit Totem:
Everyone within 30' of Soren, including himself, the other PCs, Urwin, possibly Danika and others inside the Blue Water Inn, possibly the ravens on the roof and passers by all gain 8 temporary hit points.  The center point of the effect moves wildly 60' at a time over the next minute (not staying on Soren), potentially affecting other targets.  (The Temp HP last the whole day, but for the next minute, all targets also have advantage on STR saves and checks).

It is not enough.  Nothing can stand before FIRE.  Everything must run from it or perish.  He recalls the female voice, the inexorable weight on his chest, the cackling.  The Windmill creaking like the broken world.  Soren reels and is only just barely able to compose himself enough to don his gear.

Throwing open the door, panting and sweating, Soren stammers in a hoarse voice.  "Burning... it was all burning..."  There are tears in his eyes and he chokes back a sob.  "I... I think it was the witch.  Morg... Morgantha?  Her.. or some unnatural fiend.  S-stole my sleep and filled it with nightmares.  Fire.  And the Windmill, grinding and creaking.  I think she... she must be there..."  Shockingly for a soft-spoken person, Soren's voice has risen to a shout.

"Silvanus help me.  I must find... must find shelter.  Sanctuary."  He looks around in panic, raving like a madman.  "The cathedral.  Saint Andral's.  Father Lucian... the mist was kept at bay.  The Morninglord.  Maybe... maybe...  Long ago, it is said Silvanus walked the world in friendship with the Lord of Dawn..."  In a lurching gait, Soren rushes out of the Blue Water inn, running when he can, walking when he must.  Towards the cathedral of Saint Andral's.

Burr is awake.......it was hard not to be after that....

He hastily wrapped a bed sheet around himself and moved out the door after Soren but tripped over at the door step and face planted as Soren moved out of the inn at speed.

He looked around in confusion and retied the sheet.....had someone knocked?

He looked toward Zefla and Miles room, rubbing his head...

Urwin Martikov watches Soren with alarm as he bursts from his room, makes his declaration and then runs down the hall and toward the stairs.

”Master Druid… please, take hold of yourself.”  He will attempt to arrest Soren’s flight and stop him in the hall as he passes by.  

If resisted, Grapple:  18

Soren's Acrobatics to contest Urwin's grapple, at disadvantage due to one level exhaustion:  9

The spooked druid weaves unsteadily but bypasses the innkeeper, slipping out of his grasp as he stumbles his way towards the exit.

Zefla hears and then watches Soren as he appears mad and out of his head as he spouts off nonsense that must have been a nightmare.  As Urwin attempts to stop him, she holds her breath, but the wiley druid slips past and stumbles away.  

She looks to Urwin and then back towards Soren and then to Urwin, "I'm sorry, but I have to help my friend.  I'll be back soon so we can chat!"  She heads back in her room to grab her stuff and then runs after Soren, at least knowing where he is headed if she loses him along the way.

Giles grabs his pack and gear, saying quickly out of the side of his mouth, “Here we go…. No rest for the weary!”  And he chases after Zefla, and Soren, wondering what bee got into his bonnet.  

As he rushes outside, IF Soren sees the ravens back on the roof, he slows to a trot, a stray thought intruding on his frantic haste to make for the cathedral.

I seek wisdom from Father Lucian on this... this haunting.  That and the protection his holy den offers.  But perhaps the ravens may know.  They knew of dark druids in the forest and of the darklord's dominion and the futility of Vallaki's attempts to pretend him away.  Perhaps they know of... this?

With Speech of the Woods, he addresses the ravens (if present).  More collected and stammering less than he would when speaking to other humanoids.

"Sharp-eyed, black-winged friends, know you of the windmill to the east?  Who resides there?  Some witch or fiend has poisoned and cursed my dreams with my greatest fears of all-consuming fire, robbing me of natural sleep.  Behind the hellish flames creaked a windmill.  East of the great Pool and waterfall, we had an altercation with an old woman pushing a cart who was not who she appeared to be.  A witch, Morgantha.  I fear this is her revenge."

Inside, all of you see a lumbering shape following Soren.  It seems to coalesce out of mist, bones of vapor taking the form of a massive, spectral grizzly bear skeleton.  It lumbers silently after Soren as he flees out of the Inn.

[Looking over the rules for the Spirit Totem, it looks like the temp HP do last all day, but only for those who were within the radius when the Totem first appears (not those who are later picked up by a mobile aura.  And the advantage on STR saves and checks only is in effect while you are inside the aura.  Also Soren may have some control over who gets that bonus, as it reads 'you and your allies'.  I am not random strangers picked up in the aura would be subject to the bonus.

The spirit creates an aura in a 30-foot radius around that point. It counts as neither a creature nor an object, though it has the spectral appearance of the creature it represents.

As a bonus action, you can move the spirit up to 60 feet to a point you can see.

The spirit persists for 1 minute or until you’re incapacitated. Once you use this feature, you can’t use it again until you finish a short or long rest.

The effect of the spirit’s aura depends on the type of spirit you summon from the options below.

Bear Spirit. The bear spirit grants you and your allies its might and endurance. Each creature of your choice in the aura when the spirit appears gains temporary hit points equal to 5 + your druid level. In addition, you and your allies gain advantage on Strength checks and Strength saving throws while in the aura.

Above is some relevant text.  

Regarding the movement of the bear spirit:  It has to be a point Soren can see.  So if the intent is that Soren is 'involuntarily' using his bonus action to move the spirit (my interpretation of your statement that the movement is random) the Totem will still need to move to a place Soren can see.  I will presume the Totem is following Soren down the street unless told otherwise.

Also, per the description, the Totem is visible.]

"I... yes of course.  Please, retrieve your friend before he does something foolish.  This is exactly the kind of attention you do not want to attract in Vallaki."  Urwin Martikov watches with concern as Zefla and Giles follow after Soren.

Outside, Soren does indeed see a pair of ravens perched over the eave of the Inn.  One cocks its head quizzically at him, while the other nods and responds.

 When the Spirit Totem tumbles out of the inn, a surging mass of misty, spectral bones in the shape of a great bear, the birds take flight and scatter.

 If Soren continues toward the church, he finds the streets mostly quiet under the grey skies of a Barovian dawn.  There is still moisture puddled in the streets from the heavy rains last night.

Burr sighs and wraps the sheet tight around him and marches after the others in his makeshift toga with a sour expression.

Zefla's eyes widen as she sees the bears form materialize and then follow Soren.  She almost stops in her tracks, but worries that this new thing, this bear creature was after Soren and she doubles her efforts to reach him.

Feeling a bit stronger than usual she runs out of the inn after Soren and about runs into him as he is talking to someone that isn't there.  She grabs hold of his wrist with one hand, and draws her sword with the other, pointing it at the bear-thing.  

"Wh-what is going on?!  Is this creature going to eat us?  Who are you talking to?  Why in the nine hells did you go barreling out of your room like that?!"

Soren nods grimly as he receives the response he had feared from the ravens.  There had been a mysterious witch that Soren's elven mother had called a "green hag" who had once taken up residence deep in the marshy sunken forest in the far reaches of Neverwinter Wood.  Even the band of elven warriors and mage sent to root her out had only caused the witch to relocate out of the forest to the Mere of Dead Men on the coast to the southwest, laying a curse on the elves as she left.  That had only been years before Mount Hotenow erupted and the fiery inferno of ash came crashing through the trees like a tidal wave...  and yet, Soren senses, the cackling witch from his nightmares last night may be worse still.  Nevertheless, he begins to calm down...

As his spectral bear appears in the street and alarms the ravens, Soren calls out, chagrined.  (Speech of the Woods)  "Thank you for your counsel, my avian friends.  No need to be frightened of Osk, my spirit bear.  He is benevolent and strong, and his brief presence only strengthens my friends, among whom I count yourselves.  His skeletal appearance seems to be a manifestation of the curse laying on this land.  It is not natural for him to appear so."

Feeling Zefla's hand on his wrist, Soren turns his haggard but determined face towards her, but does not cease his trot towards Saint Andral's, with the bear spirit loping beside.  (Common)  "Zefla Shadowquick.  I was addressing you and Urwin and the others before, and the two ravens above us just now.  There is no need to be alarmed at Osk, my spirit bear.  He only strengthens my allies during his brief visits, yourself included.  In my mind and soul, he is not skeletal, but rather the ghostly spirit of a brown-coated grizzly bear.  His current appearance is yet more evidence on the curse which afflicts this land.  I was alarmed at the fiend who captured and poisoned my dreams last night and reached out to Silvanus for aid.  Osk is who He sent to help me."

He takes a breath, still walking towards the Cathedral.  "But this fiendish witch who did not allow me to rest...  she was there.  Right there.  And yet not.  Somehow she held me down and inflicted endless nightmares related to... what I fear most.  And behind the nightmares, a great, creaking windmill.  I now suffer exhaustion despite a full night's sleep.  I must find respite from this fiend of a witch, who may be Morgantha.  The one who was carting away a child from the village of Barovia.  I believe her and other witches to live at the windmill we saw off the road during our journey here to Vallaki.  The ravens confirm the murderous witches who live there..."  Soren pauses uncomfortably, recalling Zefla's copious gobbling of Morgantha's pastries.

"Father Lucian at the cathedral.  He described how unholy things could not penetrate there and the mist seemed to confirm his words, being held at bay.  I must ask him if I can take refuge there, if even for an hour's rest.  Perhaps again later tonight when we sleep again.  He may even know of the witches at the windmill.  If you were me, you would never wish to go through a night such as the one I have just experienced.  Please believe me, Zefla."

Giles jogs up to Soren, taken aback by the skeletal bear spirit, but quickly gathers himself as they are talking.  “Father Lucian.  Right.  Perhaps we should have a talk.  Do we need to take care of Morgantha, Soren?  What the hell was in this dream again?”  He listens carefully, recalling his own dream of being sealed into a wall and looking out through a small hole…. He readjusts his leather armor and buckles, gear as he’s listening, now fully awake.

Burr shuffles up after Giles after a number pf wardrobe malfunctions that scandalise any early risers, " You've had a bit of a turn, my friend."

" Lets go speak with the priest..."

[* Regarding early risers, there is only one other room in the hallway where your rooms are located and it is empty.  You've been told Rictavio is staying here somewhere, but otherwise you are the only guests.]

Zefla calms down a bit but raises an eyebrow to Soren, "You're talking to the ravens?  Why?  I mean, did they have anything to say?"  As they walk, she listens to Soren.  "I do believe you, Soren.  But I wonder, should we visit this windmill and see what we can do?  I would hate for you to go through that again...or me..."  

She's quiet a bit as they walk but then wonders aloud, "I wonder if Father Lucian would know anything about this nightmare, of others have come to him about something similar..."

As you are rounding the corner from the inn to head toward the church, there is a creaking sound as a wooden door opens in one of the homes along the narrow road.  A bearded Vallaki commoner steps out into the street with a bucket.  He recoils, first at the unexpected sight of the four of you just outside his door, then again at the sight of the bear.  He retreats back with a gasp, dropping his bucket of nightsoil and slamming shut the door of his home.

The party continues west through the empty streets of Vallaki toward St. Andral's cathedral, Zefla and Father Giles fully equipped, Burr wrapped only in a blanket, and Soren in an as yet undefined state of dress.  By their side, for the next half minute or so anyway, is the Bear Spirit summoned by Soren.  While its appearance is indeed startling, Burr, Zefla and Giles cannot help but notice the spirit seems to radiate positive energy... they feel stronger and more secure in its presence, however chilling it may look.  Soon it fades away into the morning air, but the feeling of safety lingers [Everyone retains the 8 temp hp until their next long rest (or until losing them to damage, whichever happens first)].

Arriving at the church, you see a handful of tired-eyed villagers emerging from the steepled structure.  Father Lucian is on the steps with them, offering kind parting words to each of them.

'Thanks again for coming.'

"Get yourself some rest dear.'

'Blessing upon, my child.'

'I will see you again this evening.  Tell your sister I will pray for her improved health.'

As the last of the villagers depart he turns his own bloodshot eyes to yours, stifling a yawn.  "Ah.  Blessed morning unto you, travelers.  Were you here to check in on Ireena?  I can assure you was quite settled in, though I can rouse her to tell you herself."

"Ireena... right.  Father, why do you look so tired?  Does your service start that early in the morning?"  She takes a look around and then back to Father Lucian, "No, you don't need to wake her, we trust she slept well.  Actually, my friend here has some unsettling news."

And she backs away a bit for Soren to come forward, or anyone else if they would rather.
