Treant

Details as per Monster Manual. These sentient tree-beings live in certain woodlands of northern Thuria. Their origins are uncertain, but it is supposed that they can only develop in wooded areas whose soil is suffused with ancient magic. A small number of large, ancient treants lives in the Forest of Grugach, where they enjoy good relation with the elven race unique to the area.
