Pomab's eyes fill with terror as Alalla stalks closer.
"No, no wait!" Alalla's fiery sword thrusts forward with all of her considerable strength behind it. Multicolored lights flash as Pomab's magical wards try to keep the strike at bay, but Alalla's own eyes, wings, and sword flare with unyielding and merciless heat, and the weapon slides forward through Pomab's gut.
The man's eyes begin to smoke as he is incinerated from the inside out.
"No! I was promised..." He shudders in pains.
"You-" His legs buckle, but Alalla's adamant grip on his burning clothes holds him up. A scream rips from his throat, and then he becomes a pile of ash, though it looks as though there may be some items of worth mixed in with the remains.
Even with his body destroyed, Alalla thinks she can still hear his voice calling out in denial. Whatever power in life he received from Belhifet, it is unlikely that Pomab has much pleasant to look forward to in the afterlife. Also, there's is a door set into one of the crates in the small room. It seems oddly fuzzy around the edges, as though it doesn't quite fit.
With Pomab dead, the guards outside immediately begin to lose coordination, as though they have less reason to fight, and are easily dispatched.
OOC:
Pretty much everyone takes some damage that last round, but at this point the baddies are all easily wiped up - unless for some reason you want to keep one or more of the fiends alive.
Don't forget that Pomab has some loot!
