Eikthyrnir, the White Stag of Yggdrasil

Eikþyrnir is the sacred white stag of Yggdrasil, thought to inhabit the grounds of Valhalla, consuming the leaves of Yggdrasil’s highest branch, Laeradr. Eikþyrnir draws his strength from Yggdrasil, providing him with the means to produce a mysterious fluid (thought to be the source of all rivers flowing through the realms) that drips from his antlers and into Hvergelmir.
