Treant

Treants are creatures found in the Dungeons & Dragons roleplaying game. They are also a level 6 unit for the Sylvan faction in the computer game Heroes of Might and Magic V

Treants are sentient trees with human characteristics. They are typically portrayed as protectors of the forests and antagonists to industrialization and despoiling of nature. They are typically allies of druids and fey, opposing malicious races such as orcs.

Creative origins
Treants appear to have been inspired by the talking trees of many of the world's folklores, as well as the Ent from J. R. R. Tolkien's world of Middle Earth. See tree (mythology) for more information.

The name "treant" comes from combining "tree" and "giant," and is usually pronounced /|tree-ant/.
