Hidden Academics
From Jenny Everywhere Wiki
The Hidden Academics of the Tower of Yqwsl were among the “greatest dimensional scholars” of the Multiverse.
On the topic of the widespread nature of Halloween in various permutations, they speculated that “some unwary dimensional traveller accidentally warped back to the creation of the Multiverse itself (an event which is, in itself, hotly debated) and dropped a pumpkin, or perhaps a ghost, thus sparking the whole thing”.
