In the Dungeons & Dragons role-playing game, the Dark tree is a Plant. It resembles a cypress tree, but in its bark is a fiendish, evil-looking face, and two of its branches are gnarled, wooded, spindly arms.
The Dark tree dwells in warm jungles and waits for intelligent creatures to wander into its reach. It attacks in whatever way it can with its two arm-branches, and once its prey is dead, it drinks their blood.
Dark trees are neutral evil in alignment.
