Breidablik (ブレイザブリク Bureizaburiku) is a legendary relic that appears in Fire Emblem Heroes.
Breidablik is a legendary relic that has the power to summon Heroes from other worlds. Anna summons the Summoner using the relic and hands it to them for safekeeping when they are attacked by Embla army. Much to the surprise of Anna, the relic resonates with the Summoner, allowing them to willingly summon heroes from another world. Anna entrusts them to use Breidablik for good.
Though it is not seen in game, the opening movie for Fire Emblem Heroes shows the relic as white and gold handgun-like object that "fires" heroes out from it. Orbs are used as ammunition, serving as the fuel to fire heroes from it.
In Norse mythology, Breidablik is the home of Baldr. It is said to a heaven-like realm, where only the purest of souls may reside.
