The Sword of Zimran
Marthra is one of the The Swords of Power. It was created by Zimran, one of the seven great mages that rose into prominence during the Age of Enlightment. Marthra was lost in time after it came to be in the possession of Mithria, a war cleric that wanted to discover the ways to end war quickly and avoid prolonged seiges, assaults, and endless preparations for border defenses. When he learned of the power of this sword, he quested for it until he could take it and learn all it had to share. In so doing he gave up war for the pursuit of knowledge, and passed on defensive strategies so that he would be unmolested during his research. The sword was thought to be lost when he ascended to the heavens, though it is said that it was promised to a paladin.
Recent events have it falling into the hands of a notorious ranger named Aoife, who used it during the Day of Daniel to destroy the dynasty of the Sun King and establish an older Imperial line on the throne. It is now thought to have been destroyed in the pitched battle for power, during which time there are witnesses of great warriors, fell beasts, dragons, and tremors in the weft of the fabric of our universe.
