The Norns
Rarity: Unique
Element: Nature
Flavor: Ber
The weavers of fate alter destiny to suit their whims.
Since the new update involves prophecies and Norse mythology, I think there's room for the Norns with some interaction with Veleda, prophecies and maybe some other towers, like yggdrasil.
However, I don't really have a full idea here. Feel free to suggest ideas.
