Surdrassil

In the Aeon of the Champion story series, Surdrassil is a world-tree that sits on the Norma Galactic Arm of the Universe, a great deal of light years away from Yggdrassil, but less from Nordrassil. It houses the planet Prarvis, homeworld of the ogres, orcs, and recently the Eldari following the fall of Mobius in -1,559.

The world-tree and its planets have been under attack from the void eldritch Cxuirva since Mythos, though it is either a slow or weakened abomination as it is yet to conquer the planet, and has sought the aid of mortals (both ogres and orcs) to take over the Throne of the Elements in order to unleash chaos across Prarvis.
