Environment any
Organization solitary

While most examples of symbiosis are paired species that have slowly evolved a beneficial relationship, a narrow category of symbionts— referred to commonly as symbiends—have the ability to bond to and enhance nearly any other creature, feeding off and even influencing their hosts.

Though spread across the galaxy, symbiends share a number of biological similarities that hint at common origins, or at least suggest some measure of engineering in the distant past.

Despite the impressive abilities they grant to hosts, symbiends are almost helpless on their own. They communicate empathically with their hosts, while a rare few are also sentient and able to speak with—and even overwhelm—their hosts. Once a symbiend has been removed from a host, it refuses to rebond to the same host, preferring to find a new creature more invested in the partnership.
