Weave

Similar to the Weave of the Forgotton Realms, it's essentially a web of raw magic imposed by the divine, and it's accessible to mortals to enable spell casting and the existence of magical items. It coexists with the Shadoweave.

Items such as Mythallar contained an immense amount of raw magic and allowed for extreme uses of arcana without reaching into one's being (as long as they are withing the radius of effect).
