Valcentica is an RPG set loosely (very loosely) in the Harry Potter continuum. It is notable for being a pit full of Sues and its near-total separation from Harry Potter canon.
Agents Kitty Callahan and Alec Trevelyan were sent to deal with the canon-destroying monster that it had become, receiving additional, unofficial help from Agents Rena Chang and An-chi Tsai. Eventually it became so insane that the tenuous link to Harry Potter canon finally snapped, rendering it a separate, minor continuum that functions a lot like Potterverse, but not quite. With the removal of the Sues, it is no longer deemed a threat.
Agent Trevelyan has offered some of the less-Sueish students jobs in the PPC if they so choose.
