The Elder Evil Tree is an Elder Evil Tree from the RuneScape continuum. He is head of the Disturbing Acts of Violence Department's Intelligence Division.
The most recently appointed department head, the Elder Evil Tree is an ambitious fellow. His arch enemy is the Spirit Tree, and it's believed the Elder has his eye on his job.
While probably not, in fact, evil, he does tend to act in a suspicious and at times disquieting manner.
