Void Leech

The Void Leech is a presumably parasitic creature that resides within the "in-between", in particular the Void.

Physical Appearance
Despite the name and implications of it, the Void Leech's appearance resembles that of Earth Cephalopods such as squid and cuttlefish. It has a circular body, with its elongated circular mouth making up half of its total body size. At the end of its abdomen are a set of pectoral fins, used primarily for locomotion through the atmosphere of the void.

Behavior
The Void Leech, like its namesake, is primarily a parasitic creature, and is often found latched onto larger organisms found within the In-Between. Detachment of the creature is almost impossible once it latches onto a host unless the creature itself has either satisfied its hunger or is killed.
