—Anna talking to Alfonse
Once sealed away in Vaskrheim, Anna summons Kiran by using the relic and then hands it to them for safekeeping when they are attacked by Embla army. Much to the surprise of Anna, the relic resonates with Kiran, allowing them to willingly summon a hero from another world. Seeing their potential, Anna entrusts them with Breidablik to use in favor of the Order of Heroes.
During the campaign against Múspell, the Breidablik emitted a light pinpointing to an unconscious Fjorm. Further on, Gunnthrá informs Kiran that Breidablik, along with the stone Snjársteinn, is needed to perform the Rite of Frost, which, after being given to them by her, guides the order to the temple of the Rite.
In Norse mythology, Breidablik is the home of Baldr. It is said to be a heaven-like realm, where only the purest of souls may reside.
- While little about the working method is known besides Orbs being used as ammunition to fire heroes from it, Kiran once told to Merric that its power "ties the skies together".
- Furthermore, Kiran explained to Sue that they cannot choose who will be summoned, as the connections that call Heroes from other worlds are rare, but if they exist the Hero will eventually come but at an unknown time.
- According to Fjorm in Book II, it has been granted the ability to "control entire worlds" thanks to the Rite of Frost, which has completely covered it in frost. We have yet to see this happen, however.
