First Norse version of S.H.A.Z.A.M
Instead of the Rock of Eternity, the host of these powers or the MC gets summoned to the World Tree Yggdrasil where he meets the beings that live on it (The Giant wise Eagle, the Hawk Veðrfölnir, the squirrel Ratatoskr, the four stags, the Norns and the dragon serpent Níðhöggr)
Get's put to a test by the Yggdrasil using Mimir's well at the bottom of one of the roots of Yggdrasil.
Upon passing the test, can summon/channel the powers of the gods.
