"Very well, if death is what you seek, so be it." Kazri slashes the cultist on her right with her sword, and bashes the one on her left to knock it down.

Attack1: 19 Damage: 14

"Sounds good,  we regroup outside and move as a team. Let's go."

Chill handled his crossbow and readied to follow after Krom.

Kazri cuts two of the cultists down while she knocks the third onto his back.

(OOC: Slight addendum of action to previous post.)

Seeing the others rush off to make good on reinforcing Kazri's position, Rhogar looked about ready to do the same, but then thought better of the idea and looked once more to the entryway revealed. "Someone... needs to be in position to cut them off from the Cistern. Just in case. For I doubt Kadoth was alone in escorting prisoners below." He says more to himself than anyone left lingering in or near the room. And so with his mind made up, Rhogar mentally bids Gorrah to join him as they take the passageway by the fire, double timing it to the northwest tower.

If from there, he sees no cultist trying to sneak down into the cistern, he leaves Gorrah behind to keep overwatch there while he rushed the stairs, taking them almost two steps at a time in his hurry to find some access the walkways along the walls of the castle.

It takes a round or so for Krom and Chill to head back out to where Kazri is.  Chill a moment behind as he stopped to lock the door.

Does Rhogar still have a cultist over his shoulder as a "Guide".  And to clarify, is Kadroth tied up unconscious in the room with the speaker?

Kazri still faces several foes, 3 with scimitars as the one she knocked down gets back up.  The other 2 move in and they all attack!  The 3 bowman also continue to fire, one finally hitting the mark as Kazri can't dodge, parry and shield block everything coming at her!

As soon as he manages to reach Kazri, Krom shouts a battle cry while swinging his hammer at the nearest cultist. The dwarf then chants an hymn of evocation conjuring a flaming hammer in front of one of the bowmen. Moved by an invisible hand, the hammer attempts to crush the cultist.

Kazri gets another turn before Krom and Chill show up

Rhogar heads down the hidden corridor, the man slung over his shoulder, Gorrah flies close.  The inside latch to open into the watchtower is easy enough to manipulate and open.  He enters the watchtower and looks around and sees the hatch on the floor.

It is open.

At the same time a movement catches his eye as he sees legs disappear out of view up the stairs across from him.

Kazri gets another turn before Krom and Chill show up.

Roger that. I wasn't sure if I was supposed to go yet.

Kazri keeps dispatching the cultists in front of her. "My apologies, you are not getting into the keep. That is off limits for now." (She will attack the one trying to get into the keep)

Attack1: 21 Damage: 11

Attack2: 20 Damage: 10

Kazri will also shield bash the one in front of her. "You stay down!!" (I am taking that the one to her left is prone already.)

Shield Bash (Athletics): 25

(@DM: If Rhogar still has action, then he'll Dash for the stairs and as far up them as he can, but leave Gorrah behind on the current floor.)

Kazri kills two more of the cultists and knocks the other one down.  A moment later Krom comes out and slams his hammer into the last one, killing him as well.

Krom also conjures up a spiritual hammer but the cultist on the rampart dodges out of the way.

Chill is up

Rhogar, seeing the person at the top of the stairs dashes for the stairs. He is only able to get a few feet up but he sees that it is a woman who disappears out of sight.

Chill follows after Krom and as he comes into sight of the door he sees both Krom and Kazri engaged in melee with cultists.  But when he gets closer the last melee fighter falls.  Stepping out of the castle he sees that bowman are still up on the western ramparts.

Taking steady aim he fires his crossbow at the southern most bowman on the wall.

BA - Steady Aim

Crossbow Attack: 12 Damage: 24

Chill steps out and lines up a shot and one of the bowman falls dead, a crossbow bolt embedded in his chest.

Attack: 18 Damage: 5 - Chill (1-2), Kazri (3-4),  Krom (5-6) 5

Attack: 11 Damage: 2 - Chill (1-2), Kazri (3-4),  Krom (5-6) 5

The two remaining bowman fire a couple arrows down at you but both miss.  Then realizing that they are terrible shots they look at each other and a moment later both drop their bows and raise their hands in surrender.  "We surrender!" they yell.

A moment later a door opens on the north tower and a woman steps out onto the top of the rampart.  She suddenly climbs to the top of the battlement and to your surprise she jumps off the top.  But instead of falling she flies into the air and away from the castle.  A black bird follows after her. 

Krom murmurs an hymn of guidance as he attempts to get a better look at flying woman. At the same time, he informs Kazri of the Speaker told the group and their plan free the hostages. "Rhogar has probably everything under control by now, but let's hurry, just in case." says the dwarf as he runs towards the north tower.
Even if the two remaning cultists have surrended, Krom does not dismiss the spectral hammer, he makes it float and move near the bowmen as a reminder that the castle is now under the protection of the Fellowship of the White Cloaks.

"Looks like the rats are fleeing the sinking ship!"

Chill says as he keeps his crossbow trained on the 2 on the rampart.

He then walks further into the courtyard to get a look at the opposite wall to see if anyone is there.

"We are going to need the clear the interior of the castle also and find all the hiding holes just to make sure there are no other cultists."

Without missing a beat, Rhogar continued his rush up the stairs after the woman. But between her having a head start ,and the burden on his shoulders making the climbing less than easy, hope of catching her flees his mind. Yet that hadn't stopped the dragonborn from trying, and ultimately barrelling his way out onto the parapets as soon as possible if given half the chance. Though as soon as he'd see the guards there, electricity began visibly sparking from his maw as he'd heatedly demand of the guards, "Where is she?! Who was it that ran up here?"

Kazri follows Krom back inside of the keep.

Krom makes his way towards the north west watchtower and Chill steps further out and checks the far ramparts but doesn't see any other bowman or guards. 

Rhogar climbs the steps but he is too far behind and can only watch as the woman flies away.  In anger he turns to the two cultists on the rampart that have surrendered.  One of them yelps and explains as best he can.

"Uh, there was a woman, a tiefling.  She was a mage I think.  She stayed to herself and we left her alone.  We didn't ever see her, she stayed under the castle.  Why she was here we don't know."  The men don't know anything more than that.
