The Decempus, also known as the “tree roper”, is an invertebrate the size of a bear. It has ten tentacle-like limbs attached to a rotund body. Its large yellow eyes give it a phenomenal peripheral vision. Its large maw opens on a single row of interlocking teeth. It has a rough leathery skin which often matches the color of the trees it hangs from. Often a parasitic moss will grow on top of its head, which will make it ever harder to spot. It moves among trees by using two or more limbs to support itself. If trapped on the ground, it will use four limbs to walk, but could sit and attack with all its remaining limbs if hard pressed.
