The Dreamwalker.

Orcs pray to Mother Earth and Father Sky, but Dreamwalkers are the voices of the tribes’ ancestors.
To become a Dreamwalker, a shaman must first undertake a dream journey to the Spirit World to meet the spirits of his Ancestors. During this inner journey, the Dreamwalker must also face his own demonic heritage and destroy the Chaos within himself.
Many Dreamwalkers die during this trail. Those who survive return transformed: their body twisted and deformed by their struggle with their chaotic blood, yet having gained a greater understanding of blood magic and the spiritual realms.
The Dreamreaver is the upgraded Dreamwalker.
