In the Dungeons and Dragons fantasy role-playing game, the Oaken defender is a Plant. They resemble enormous (30 feet across) disks made of dirt, wood, moss and dry leaves, with six vine-like tentacles protruding from the rim at roughly equal intervals. The topside of the disk has what looks like a huge, angry face made of stumps and roots set into it. Oaken defenders appeared in the Monster manual IV. Oaken defenders speak crude Sylvan. They are regarded as neutral in alignment.
