Marath

Appearance
Somewhat resembles an oversized cutter knife. The blade is made from pure mithril, a silvery white metal. The enormous grip and oddly shaped, thin guard are also made from mithril, but those have been stained black by the mixture of mithril and dragon blood also used to forge its superior sisterblade Tietan.

History
Forged from the excess materials that were used to create Tietan, sword of Sigmund. It has a soulless conciousness that allows it to identify its wielder, shielding that person from surveillance and mind magics. Makes an exception for you as the master of its wielder.
