Erdolliel flings the light source into the next room and moves forward to get a look.
At the end of the long ramped hall, a grand chamber opens to a height of eighty feet. Opposite the entry is a tall octagonal column of jet-black stone, glowing with green symbols running up one of its faces. A deep pool of placid green liquid stands before the column, bathing the entire chamber in an otherworldly light.
Floating above the pool is a humanoid form with strange rubbery purple flesh, dressed in black robes, wielding a staff of red metal. Its head is hairless and bulbous, with four long tentacles where its mouth should be. Inside their heads, both Erdolliel and Kushnak here an alien voice.
"You dare to enter my sanctum! Fools. I knew of your presence, and I see your light thrown into my chamber. I shall finish what Telakin could not. Your weak minds will be a sumptuous feast, your terror a pleasing garnish!"
Though clearly alerted, if the creature has seen Erdolliel, it gives no outward sign of it. Erdolliel, however, does notice another of those alien creatures with the claws (of the smaller size) scaling the wall, lurking in wait.

[sblock=OOC]The illithid (1) is 40 feet off the ground. The other thing (2) is 30 feet up.
