Prosphirrhini are strange, one-eyed, multi-limbed, primate-like creatures which inhabit the jungle canopies of their native planet. The creatures are omnivorous, and use their highly sophisticated senses and extreme agility to capture small prey. The Prosphirrhini live in elaborate treetop warrens made from masticated leaves, branches, and other natural materials. The tunnels in these networks may extend for miles. They show signs of an emerging intelligence, as complex social behaviors have been observed, including marriage, religious, and death rituals.
