Mark of the Huntsclan

All Huntsclan members are born with a birthmark in the shape of a coiled dragon on their body. This mark is often how a baby is found and taken by the Huntsclan, as was Rose.

Though it never collaborated in its origin or purpose. It's unknown if the Mark grants the user any magical powers or not, as some fans think the Mark is responsible for the futuristic technology of the Huntsclan.
