Animated trees were regular trees, brought to life by druidic magic or through the command of a Treant. These magical plants did not possess intelligence or sense of self on their own, but did as they were commanded, similar to Constructs.
Despite their lack of sentience, animated trees were nonetheless formidable opponents due to their sheer size. They used their larger branches and trunks to slam into hostile threats, with enough power to kill the average Mortalkind outright if not trained in combat.
