Elf

Elves were magical humanoids who existed, in different forms, in many universes.

One incarnation of Jenny Everywhere was an Elf, meaning, in her case, a tall humanoid with long hair and slightly pointy ears. (COMIC: Governing Council)

In the Collapsed Cosmos, Elves were present in the Red Lion Inn, alongside Orcs, gods, demons, and many other curious characters, when Jenny and Glendalf visited it as they fled from Faerie to escape the Wild Hunt. (PROSE: The Hermetic Garbage of Jenny Everywhere)

Elves existed in the Prime Universe, appearing to be a kind of Fae. Tero Trollgarsson initially believed that the Clockwork Cherubs Juliet-178 and Pythagoras-858 were Elves and that the Interdimensional Tavern to which they'd accidentally transported him was a “faerie-realm”. Adding to the confusion of the situation, there was an actual Elf of unknown origins in the Tavern when he said so. (PROSE: The Winter Quests)
