Castle Avernus Throne Room

At a glance

A ruined chamber that first appeared as an extravagant, giant-scaled throne room sustained by a mouldering crowned giant.

Initially appeared immense, intact, and proportioned for a giant ruler.
Contained a giant zombie wearing a crude iron crown and exhaling toxic decay.
When the giant died, the room rapidly rusted, crumbled, and shrank.
The transformation exposed a much smaller and badly dilapidated chamber.
Whether the grand form was illusion, conjuration, displaced reality, or another effect remains unknown.

Its crowned occupant is destroyed, and only the smaller ruined chamber remains visible.
