A towering, skeletal lich cloaked in tattered robes of deep violet and obsidian, his hollow eye sockets burning with an eerie, cold green flame that flickers like dying embers, standing atop a jagged obsidian throne in a cavernous, ruined cathedral. His elongated fingers, wrapped in ancient, crackling energy, clutch a gnarled staff crowned with a skull that whispers forgotten incantations, while swirling shadows coil around him, forming spectral minions that writhe in silent obedience. The air hums with the weight of necromantic power, as arcane runes pulse faintly across the stone floor, and the distant echoes of tormented souls resonate through the chamber, amplifying his aura of dread and dominion over life and death.
