>Legendary Devil Fruit in Elbaf
Calling it, this is a size changing Devil Fruit.
In addition to being on the nose for Elbaf, it's the power that shrank the 2nd moon to halt the Planetary Reversi.

The mysterious figure who stole it was Loki. He felt it was his birthright. This will allow him to board the Sunny later as a normal sized person.
They'll need to use the power to restore the One Piece and complete the Anti-Reversi.
