Damnatio Memoriae

With this spell you condemn the memory of a creature to oblivion, erasing all recollection of their existence from the minds of those who knew them with the exception of those who witness the casting of the spell. The target's identity, appearance, any depictions of the target, and any information pertaining to them are utterly purged from reality. Casting spells such as legend lore or other forms of divination will also present the new reality. Those who remember actions taken or titles held by the target do not lose their memory of the target in its entirety, but rather lose the ability to connect the targets identity to the subject of the memory. For example if a famous king were to be the target of this spell, his subjects would not lose the memory that they had a king, but would be unable to identify the man as their king, nor recall any defining features of the king they remember.
