The Lava Trees was an organism which looked like an upside-down reddish tree with flat gray leaves and roots which extended into the air. The "leaves" sensed the preys and the root-tentacles grabbed them. The tree hoisted the target into the air strangling him. Enzymes in the roots broke the body down to feed itself. If cut the trees leaked lava-like sap. They were found mainly in those areas of the Shadowlands with volcanic activity and sulfurous vents.
