Doc rushes (action dash) in (if possible using the catwalk if he thinks its to far hell stand behind Chromir and Navrine.)

((Does it look (or feel through Tremorsense) like Luna is still alive? Doubting about BA healing word on her.))

Chromir has no round 1 action (I wasn't sure if breaking the door down was an action, but without having seen the situation he had nothing further to do). "Well if Luna isn't the werewolf, who is?" 

His round 2 action will depend on what the two men do during their actions as they are before him, however what he would like to do, is if either of them show any sign of aggression, go over and recklessly bear hug (grapple) them. 19 to hit, and on a hit they need a DC12 Dex or Str saving throw.

((Does it look (or feel through Tremorsense) like Luna is still alive? Doubting about BA healing word on her.))

 oc rushes forward as close as possible to the catwalk

Cassian dashes to catch up with Chromir and Navrine, able to make it just inside the saw room before he has to stop to catch his breath. It takes a moment before the scene truly hits him. "Luna..." The one time he didn't expect the worst, here it is. Tears start to well in his mismatched eyes but he fights them back for now. Darin with bloody hands and an axe...and Baron Thorne? The noble...left his castle to help search? The paladin's mind races with questions and possibilities.

Darin let out a furious cry and lunged at Baron Thorne, his axe raised in shaking hands. The baron took a measured step back, his expression a mask of composed shock, but before the blow could land, Chromir barreled forward, wrapping his arms around the woodsman in an attempt to hold him back. Darin struggled violently, his boots scraping against the blood-slick floor as he struggled against the enraged goliath's massive bearhug.

"Why are you stopping me? Are you with him  now?"  The woodman shouted, his voice raw with anguish.

The red squares (sawblades) and the orange squares (gears and machinery) are not walls, they can be moved through, but doing so is dangerous.

Dex save (DC15) or 2d8 slashing damage if you enter, or start your turn on, a red square.

Dex save (DC15) or 2d8 bludgeoning damage if you enter, or start your turn on, an orange square.

Doc moves forward to stand on the catwalk and see what is going on, he'll check if Luna is alive, and if yes will spend his BA to heal her for 9hp.

Perception: 6

Cassian struggles to clear his mind. Darin is covered in blood, his emotions out of control...but that could be from trying to wake up Luna and shock. He murmurs an incantation to hopefully draw the woodsman's attention to himself in case he escapes Chromir's grasp. The Baron seems composed as ever. 'He just threw her into the saw.' The thought makes the paladin sick to his stomach, but he forces himself to examine the scene. Turning towards the Baron, he tries to address him as calmly as possible.

"C-can you explain exactly what you saw? And...w-why you're here? I d-didn't expect you would help in the s-search directly."

Action: Persuasion on Baron: 11

Bonus Action: compelled duel on Darin. DC 12 Wis.

Concentration on shield of faith dropped.

Doc moves forward to stand on the catwalk and see what is going on, he'll check if Luna is alive, and if yes will spend his BA to heal her for 9hp.

 Perception: 22

(extra perception check as per OOC request: 10)

Chromir will continue to bearhug Darin, (action to attempt another grapple, unless Darin looks like he has changed his mind and won't try and hurt someone. Hurting himself included). BA to extend the rage. "I am stopping you because ideally no one else will be hurt today. Even if someone here is a werewolf, that doesn't mean they have to die."

Navrine moves to block the Baron. Holding her hand up "Lets all just take a breath shall we?" 

Movement: Blocking Baron in Melee range

Action: ((Hold an attack if he makes a hostile move)) 21 to hit  8 points damage.

 Perception: 12

Chromir strained against Darin’s thrashing, and Cassian’s magic pressed with unseen weight upon the woodsman to keep him from attacking. 

Navrine knelt by Luna’s broken body, realization dawning in her widening eyes.

Above, unseen to those below, Doc stepped onto the catwalk — just in time to see a crossbow aimed straight at his friends.

And then Baron Thorne spoke.

"You ask what I was doing here, Sir Cassian?"  The baron's voice was smooth, cold, and unhurried, even as his fingers curled unnaturally against his palms.

"I was ensuring that justice was served — ensuring that these poor cretins I rule over had a culprit."  His lips twisted into something between a sneer and a smirk.

"And now, thanks to you, I see another way forward."  His gaze snapped to Chromir, his voice dropping to a growl.

"No more needless deaths, you say? Then tell me, goliath — if no one here believes Darin did it…"  

"Then the only solution that remains is to make sure that none of you leave here alive!"

The baron's body convulsed.  The fine fabric of his nobleman’s attire stretched, then split apart with sickening ease as his limbs elongated.  Sinew twisted beneath darkening flesh. His jaw cracked open unnaturally wide, teeth lengthened into jagged fangs and a guttural snarl escaped his throat.

Clawed hands flexed, curling inward as thick fur spread like wildfire across his arms. Bones popped and shifted, his posture snapping from the poised stance of a nobleman to the hunched, predatory crouch of something far more monstrous.

The change took only seconds, yet it felt like an eternity. His transformation was not a seamless, graceful thing — it was visceral, brutal, the sound of bones grinding against themselves filling the sawmill alongside the rhythmic shriek of the moving blade. When he looked up, his eyes no longer held the cunning of a man, only the hunger of a beast.

The baron—no, the WEREWOLF—threw back his head and howled.

"AAAaaaOOOoOoooOO!!!"

After all of this ... Navrine responded with a well placed kick! (readied action)

As soon as her blow landed, however, the guard upon the catwalk loosed a bolt in defense of his lycanthropic master! (readied action)

Medicine Check Results (Navrine knows the following)
05 - Luna is quite obviously dead
10 - She was killed by slashing attacks
15 - The slashing attacks were not by a blade, but rather, the claws of a beast!

Perception Check Results (compare your result against the following DC's)
05 - Luna is quite obviously dead
10 - The saw blades of the mill are not bloody at all
15 - Luna has some of that golden pollen on her from the baron's greenhouse
20 - The baron's guard is here!  He was hidden up in the catwalk, and he has a heavy crossbow trained upon the party!

The beast that was once Baron Thorne lunged at Cassian, claws sweeping through the air. The paladin twisted aside just in time, the force of the strike sending splinters flying.

Snarling, the werewolf snapped at his throat, but Cassian’s shield caught the blow with a harsh clang.

Thorne recoiled, glowing eyes burning with fury. 

Subtlety was gone.  Now, there was only the hunt.

Init — Name, AC [hp inflicted]; Conditions & Effects; Actions
17 - Baron Thorne, AC15 [8hp inflicted]; scratch and bite vs Cassian ... both miss.

Heroes are up!  After Doc's action, the guard also has an action this round.  But since the Baron leads us off on the init count.  I will sum up future rounds by starting the next round with his action (that way, you guys can determine what you would like to do after you know what he is doing).

The red squares (sawblades) and the orange squares (gears and machinery) are not walls, they can be moved through, but doing so is dangerous.

Dex save (DC15) or 2d8 slashing damage if you enter, or start your turn on, a red square.

Cassian could only watch in stunned silence as the Baron's form twisted before him, only regaining his senses when the crossbow bolt from above knocked Navrine aside. He tried to yell, but was cut off by the werewolf's viscous strikes.

"I'm s-sorry. Luna...Darin, you should run." He states surprising calmly as he drops the spell on Darin, gripping the hilt of his longsword tightly as radiant light envelopes the blade. "Chromir, I think...t-this one does, for us to live."

Action: Channel Divinity, Sacred Weapon. To hit 22, damage 4 radiant and sap

Bonus Action: divine smite for 4 radiant damage

Navrine runs up and attacks the baron.

Action: Unarmed Strike 24 to hit, Damage 8 points bludgeoning damage.

Bonus action: Flurry of Blows(one focus point) First blow 11 to hit ((miss)),  Second blow Hand of healing to herself 5 points healing.

Doc sees the guard, before the transformation. But doesn't have time to warn his friends. He throws a javelin at the guard moves in and tries to hit with another. Furthermore a spiritual hammer appears next to the werewolf and strikes! 

Javelins:

22 for 5 and crit 25 for 9dmg

Spiritual weapon:

11 for 8dmg

Chromir moves around Cassian (Dex save 19 to avoid the saws) to stand behind Thorne, as he draws his greataxe and recklessly attacks getting a strong hit in (24) for 22 slashing damage.

The battle erupted in full.

Above, Doc hurled his javelins with precision — one striking true, the other sinking deep into the sniper’s side (a crit). A spectral hammer also appeared beside the guard, swinging wide as the wounded man raised his crossbow and fired. One bolt grazed Doc’s shoulder, but the cleric held firm.

Below, Chromir surged forward, weaving* past the deadly sawblades to bring his axe down in a brutal arc. The blade struck deep, carving through fur and flesh. Thorne howled in pain. Navrine followed, her fists a blur as she struck, though only one blow found its mark. She exhaled, channeling her ki to mend her wounds even as she fought.

Cassian’s sword flared then with divine light as he drove it into the beast’s side, the radiant energy searing its flesh. The werewolf reeled, bloodied (<- at half hp or less).

Snarling, the beast lashed out at Chromir. Claws raked across his chest, and then the beast’s jaws snapped shut on his arm. The pain was fleeting, dulled by the barbarian’s rage — but the wound burned deeper than it should.

Something foul lingered in the bite, seeping into his veins.

*It wasn't clear from the map at first, but there is 10' of space on either side of the center strip of 5' 'trapped' sections.  The Dex save was not needed to maneuver behind the baron, but the visual was cool so I kept it.
