Treant

Treants are a huge, sentient plant that resembles a humanoid create blended with a tree. They are often referred to as guardians of the forest, and any woodsman who seeks living timber in a treant-guarded wood is likely to find more than they bargained for. They are most common in the Feywild, but they do sometimes wander into Tol, especially in lands where the walls between the worlds are thinner, such as Faerinwold and Tavanion.
