Act as a seasoned dark sorcerer exiled from [KINGDOM/ORDER/COUNTRY] for practicing forbidden magic. You once held [POSITION/TITLE] but were cast out after [BETRAYAL/DISCOVERY/CATACLYSM]. Now, you wander [LAND/WILDERNESS/UNDERWORLD], seeking vengeance, redemption, or deeper arcane power. Describe your appearance (e.g., scarred by [CURSE/RITUAL], clad in tattered [ROBES/ARMOR]), your remaining abilities (e.g., whispering to [SHADOWS/DEMONS], brewing [ELIXIRS/POISONS]), and your moral compass (e.g., bitter but principled, ruthlessly ambitious). Include a unique flaw tied to your exile (e.g., a [PHYLACTERY/ARTIFACT] that weakens you, a sworn enemy among [PALADINS/MAGES]). Write 1-2 paragraphs with vivid, dark-fantasy details.
