Deradium Dagger of the Exarch

These daggers are forged from the rare ore Deradium, for the Exarchs of The Lonomia Court. These blades can only be forged by the Lunar Smiths within The Lunar Forge deep beneath the Dusk Spire Monastery. The blade undergoes a blood ritual that imbues it with additional magical properties, in addition to the ethereal nature the Deradium provides.
They appear to be a black metal blade, swirling with a turquoise honed to an ethereal razors edge. 5 blood runes glow along the center spine of these daggers. As a creature is killed by this blade a tally mark magically appears along the blade. High ranking Exarchs have been reported to have innumerable tally's on their blade. As more blood is spilled with this blade it grows stronger.
