Shae's attempt at Zarahiah, as Kahan suggests, will not work due to lacking an "A." Platinum also does nothing. Tahldar begins pulling out the writings from the portable hole as Kahan spells out Zuggtmoy. Tahldar stops what he is doing because Zuggtmoy (the goddess of fungi) seems to do the trick.
As the last letter is put into place, a greenish, sickly glow surrounds the pedestal. Above you, the floating jellyfish-like creatures part ways as a portal opens between them.
Descending through it is a foul, acrid demoness resembling a human only from the torso up. This portion of her body is composed of thick rancid sheets and coils of fungus that have grown into the shape of what would, otherwise, be an attractive woman. Four fibrous layers grow from her brow where hair should be, and her hands bear cruel talons. Her lower torso is a coiling pillar of lashing ropey tentacles and other fungus growths. Her skin is a nauseating swirl of greys, blues, purples and blacks. She appears almost alien and inhuman as a skeletal-thin humanoid shape draped and veiled in mycelium and lichen.
Her bottom half fungi and tentacles wrap around the pedestal as she descends, making you take an abhorrent step back, as she stands at least 12 feet tall and looks down on you.
Then she speaks:
"Who dares summon me from my realm?"
