#pellum

Basically, the academy wanted Pell out due to the stigma of the Pellum name being now attached to Karza, or they were pressured by certain influential Microsians (Sinessy) but they couldn't kick him out so they just... early graduated him. Really early. And now he's trying to lay low because if the rag-tag team he's in charge of now finds out their acroyear is actually a teenager who's mother still thinks he's in school. They might have opinions. Not to mention Karza WOULD recognize him... So keeping it to "acroyear" works just fine for him.
