The throne room is submerged in a rhythmic, pulsating black radiance. Shadows don't merely exist here; they writhe against the obsidian walls like living things, and the air is heavy with the metallic tang of ozone and the suffocating scent of despair.

"State. Your name, you." The command hangs in the electrified silence, demanding an answer.
