So I'm working on a character that has an item of power and I see it being really tied into the character and their identity. So I'm wondering if that deserves or could serve as an aspect. I can't think of a good way for it to be reliably compelled besides dropping it (and that seems kind of cheap) and invoking it to do its thing better is kind of redundant on the character. So should I worry about it as an aspect or should I not worry about it?

Some context, the weapon is an axe given to him by Odin for wrestling a bear in the nevernever. Its name is bjornerdyr which translates to the bear's door because he uses it to cut into the nevernever.

I'm specifically wondering if anyone has ideas for the arch. After doing a little research I'm thinking of playing up the "gateway to the west" idea and having the arch be a purposefully weakened veil to the nevernever, but I'm struggling to find a purpose for doing that (besides some demon summoning maniac)

Alternatively I was considering having all of St Louis be an accorded safe haven and having the arch disperse the magic nullification of the Mississippi River over the entire city using a giant magic circle. Think a giant warded threshold with the river serving as a battery. But when the red court was killed off and the spell targeting the Reds hit the arch it overloaded the system causing it to fail. Now St. Louis is a war zone over turf and the accords are basically non existent (or at least blatantly ignored).

Ideas? Concerns? Would that mess with the canon in the books?
