Mycozoa

Mycozoa is an Eternity Construct, and was specifically created to watch over nature, the land, and land creatures. Its physical form is a large stone humanoid creature, with no facial features other than a pair of glowing green eyes. It has a tree growing from its back.
For many thousands of years, Mycozoa served as a vessel of the evil entity Sosk'Th'Gal, restricting its corrupting influence.
In 20.42, when Sosk'Th'Gal was killed by Ayla Vanderstone, Emilio Ventura, and Onno, Mycozoa was finally freed.
