(Stalking) Peter's Creeping Shadow

Lore
Peter's shadow laughs wickedly as it takes over Peter's mind. No longer confined to its old, flimsy self, it can finally exert its influence upon the world. In this instant, Neverland begins to change from a land of dreams to a land of darkness. With its nimble guardian lost, the power of shadows will soon infiltrate every corner of this world.
