Valkyrie (Japanese: バルキリーの杖Valkyrie Staff) is the holy staff once borne by Archbishop Bragi of the Twelve Crusaders, bestowed upon him at the Miracle of Darna following his blood pact with a dragon. It is the property of Bragi's descendants, the nobility of House Edda of Grannvale, and can only be used by those who bear major Bragi Holy Blood. Analogious to the Aum staff of the later Archanea era of the world, the staff is capable of resurrecting a dead individual, albeit limited to those who in life possessed a substantial amount of quintessence.
Assumed by the descendants of House Edda to have been lost for some time, Claud found it in Bragi Tower during his trip there to pray and see the true nature of the conflict embroiling Sigurd. He retrieved it and carried it with him in his travels with Sigurd. After Claud's death in the Battle of Belhalla, it came into the possession of his child.
Valkyrie is the only one of the Crusader weapons (not counting Loptous, which though bound by Holy Blood isn't a Crusader weapon) to not reappear in Awakening; its counterpart Aum also did not appear in said game.
However, the fortify staff in Awakening does closely resemble it physically.
Officially romanized as Valkyrie, literally "Valkyrie Staff". From "valkyrie" (Old Norse: valkyrja), a term in Norse mythology used to refer to lesser deities of Norse mythology tasked with escorting the most valiant of deceased warriors to Valhalla. In Genealogy of the Holy War, all staves have the の杖 suffix.
↑"Tailtiu: Hmm... So can it bring back my sweet grandma? Claud: Well, no it can't. You see, it has certain limitations, so it won't work on everyone. You see, we're all born with this life force. It's called 'quintessence' and... Tailtiu: Huh? You lost me. You're *yawn...* puttin' me t'sleep." — Tailtiu and Claud, Fire Emblem: Genealogy of the Holy War
