The main idea here is the appearance. It has a decorated ring that channels the energy, and a fitting logo to go along with its byproduct.
Aside from visuals alone, much like magic casting, upon touching it you can fire off a (sort-of) lightning blast, with of course raw spirit energy.
I’m imagining it being created as a way for those without magic to use it, or alternatively, a way for people to throw around a different kind of magic than the one they have. Sort of a substitute to magic circles, and possibly an experiment by the Order of Aesir themselves, the player seems too attached to it for that to be the case though.
Do I believe this? Heck no, just putting it out there. Feel free to disprove.
You know, that does add up. But who’s to say how it was created? Obviously you have for sure the implication that a god imbued it, but anything else could have really happened.
