The tattered cap of this giant mushroom swells into shape as it changes from the shape of an ordinary tree. The air ripples around its narrow stalk as it rises slowly into the air.

Warp drifters are fungus tree-mimics that feed on the natural bio-energy of sentient creatures. They often conceal themselves near populated areas and employ their psionic powers to ambush travelers. Their behavior and tactics suggest a considerable intellect, but attempts at communication have proved futile. Warp drifters understand Common and Sylvan, but cannot speak.
