Dragon scale (Disallowed)

A dragon’s scale (ryurin) is a stylized charge from Japanese Mon, meant to represent a portion of a dragon’s armored skin.  Its point is to chief by default.  The dragon’s scale is found in the Mon of Houjou [Hawley 57], but has not yet been dated to period; pending evidence, the dragon’s scale is no longer registerable.
