X of Swords, a tournament held in another dimension for the survival of Krakoa.

Hellfire Gala, a giant party filled with politics, intrigue, where mutants rub elbows with heroes and some villains from the rest of the Marvel universe. 

Those are a few Canon events likely being reworked and customized for the RP.
