Relkath of the Infinite Branches

Relkath of the Infinite Branches was a giant treant deity in the Yuir elven pantheon who was chaotic and unpredictable. Forests were said to sprout wherever he touched the ground. Whilst he was known to defend the Yuir elves, he also took action against some of them, turning priests into trees and villages into forests. There are some elves who believe that Relkath is merely an aspect of Rillifane Rallathil. Relkath, aspect or discrete entity, was thought to cease to exist with the downfall of the Yuir elves.

As of the Post-Spellplague era, Relkath of the Infinite Branches is said to be an Archfey , at least by the fey of the Moonshae Isles.
