An ancient undead ruler forged from forbidden magic and celestial power. Draped in ornate white-and-gold robes adorned with glowing arcane crystals, the Eternal Arcane Lich commands the dark cathedral with overwhelming presence. The flowing garments, intricate gold filigree, and luminous blue energy create a contrast between divine elegance and terrifying necromantic power. Designed with a cinematic dark-fantasy aesthetic inspired by legendary boss characters and gothic fantasy worlds.
