Fulmos (humus arduus) The Fulmos is a large fungus that grows high in the Balandic Mountains. It reproduces by releasing tiny spores, which attach themselves directly to the rocks. These fungi feed on rotting plant material and nutrients in the rich volcanic soil. They have also been seen attached to carcasses and skeletons of perished animals in the area. Fulmos can grow up to 91 cm in height and are highly adaptable, living in some of the harshest climates in Solturna and all throughout Orcura.
