Edmund spins his glaive and and delivers a nearly fatal blow to the dwarf on the podium, who stands in shock as he bleeds down his front. He raises his unholy symbol again and energy crackles around it, only for his last stand to be cut short. There is a loud boom and a new hole blooms in the dwarf's shoulder, as he falls over, bleeding on the wooden stage. The unholy symbol clatters to the ground next to him, the energy fading away harmlessly. At the far end of the room, Ed sees Robert standing triumphant.

Asma shanks the human on the balcony in the shins and he growls, only for Christof to strike him with the pommel of his sword. The man crumples to the ground, unconscious as Christof steps over him to threaten the dwarf with the switch. On the other side of the dwarf, the guard captain takes risky action to draw a wand from her bandolier and point it out over the battle, giving the two foes nearby an opening to attack her. She avoids the club swing from the human on the stairs, but the dwarf nicks her with his switchblade as a lance of strange white light launches across the room. The light punches into one of the human cultists as though it carries actual physical force. He looks like somebody dropped a sack of hammers on him. Seconds later, Claudia's whip wraps itself around his neck and strangles him. He falls to the ground as Claudia smoothly and professionally whips her weapon loose.

Reed pushes past Asma and takes a swing at the dwarf, but his blade hits at a bad angle and doesn't pierce the dwarf's protective gear. The Blue Rose Knight hops the railing to join the fight below, but fumbles and lands on his rear. Looking a little embarrassed, he scrambles to regain his footing. Dean moves up to the ledge where the knight hopped over and levels his crossbow, nicking one of the cultists that are still standing. The Calistrians move up, Huemes cutting into one of the Asmodean dwarves with a solid slash. Ardok follows up, driving his gandasa home. The dwarf is left barely standing.

Two crackling rays strike Mindy and Edmund respectively, but the third standing cultist steps away from Claudia and points at Edmund. "Kill." He commands forcefully. Claudia takes a brutal blow to the side, but she rolls with it, showing impressive durability for her appearance. Another strike from the dwarf up on the landing cuts Lorey, but she is not badly wounded yet. At the foot of the stairs, Ardok takes a hit as well.

Arrows and bolts fly across the room, and the knight who fell down grunts in pain as one thunks home. One flies past Ed, the other is deflected by his bone.

Argyle chants loudly in a hellish tongue, his voice reverberating across the room. Another wave of cold air blows through the chamber and the torches nearly go out, but the flames come back after it passes. Edmund feels a deep cold sinking into him as he continues to obstruct the altar. He feels it to his bones, and his body aches for warmth.
