(Flame strike will not burn the buiding. It seems taht there are many around the I-J by 9-10 one, but you should cast it after Jaina has been telekinesis'd away)
Jonathan comes over to join the rest of you, but on the way he is stabbed in the back with a polearm. He falls and rolls and countersweeps with his quarterstaff, kneecapping his attacker, who stabs Jonathan again as he falls forward. Jonathan gets up faster and tries to drive the quarterstaff into the vampire's heart, but the vampire rolls out of the way.
Kelnar summons webs to black the back enterence, then raises his hand and makes a pulling motion, pulling Jaina across the room towards him. She hits the edge of the table hard, grunts, and collapses.
As soon as Jaina is out of the web, Emcat calls heavenly fire to burn these abominations from the earth. (the flame strike will destroy the web, but the burning web will do 2d4 = 8 (yay synergy) to each vamp in the area)
You hear multiple Vamps scream in agony as the fire burns them, and beucase the air cools faster than their flesh, Kelnar can momentarily see that there are 4 of them there (all alive but hurt badly), one of whom suddenly runs at inhuman speed towards Jonathan, who you see get thrown into the wall. He bounces off and it appears that the vamp tries to hit him, but instead puts his fist through the wall. Jonathan falls to his hands and knees.
A vamp with a polearm jumps on the table (G11) to menace those hiding under the table.
