Oathkeeper (Earth-19999)

The Oathkeeper is the sword used by Jojen Reed, used in his tasks of keeping oaths with the Elder Gods and Mortals. He continues to wield the sword even after he abandon the Elder Gods to aid Asura and Shujinko on their quest. It can be found as a Relic in Mortal Fighter: Ragnarök's Story Mode.

It is also an Trophy and Achievment icon on Mortal Fighter XI, even though Jojen does not appear in the game.
