This weapon was forged by Clanngedon himself for Tyr. Tyr only allows his chosen mortal avatar to wield these blessed blades.  ras has no idea of this and he think that most of the spells that are blasted from the blades are simply countering magical object being destroyed by his attacks.  
  
The previous owners were Tyr and Clanngedon.  They always come together to decide which of their two orders deserves this weapon  the most. Ras was chosen by both because of his striving attempts to make a difference and the way he is doing it.
