"Elven Swords" as they are called are the strange foreign daggers made of silver, trimmed with gold runic text and a titanium tip. These swords have existed in abundance since before the Xeliopurge Bombardment.
Elven generals dual weild these on the battlefield often, bring a flurry of death upon those who cross their paths. Assassins and scouts also are seen utilizing them to stealthily kill others.
Over 500 of these daggers were found concealed in a crate within a tomb found deep in the Velani jungle. The architecture of the tomb doesn't match any of the architecture found from anything else that could have existed at a time, leaving where they came from a mystery many elven philosophers have contemplated since they were found at the beginning of The Kingdom Era.
