Robeskin
this was the term used to describe a thin, living membrane developed by the Yuuzhan Vong as a portable cloak. The robeskin provided the wearer with minimal protection, but served to cover their body. The robeskin received food by feeding on the bodily secretions of the creature that wore it. Skin cells, sweat, blood, and skin oils were all ingested by the robeskin as it hung around its owner's form. In return for this sustenance, the robeskin kept its owner covered from the elements, and could even assist in the healing process if its owner were injured. By consuming the pus and effluvia of an injury, the robeskin helped prevent infection while using its own curative properties to help its owner heal quickly.
