Rey has described an alignment system (Allegiance) that is determined by the spells you choose to learn rather than a simple, preselected choice. Your spellcaster can draw their power from either dark or light energies (or a combination of both). It's not certain yet if there will be a mechanical consequence of your characters Allegiance (over to you Rey).
bursts and flare system Rey alluded to in an earlier post.
I'm looking to develop icons (and a visual identity) for each magic class. Maybe the illustration style will differ for each energy type? but I haven't really taken this idea too far yet!
In the finished book, spells will be clustered by magic type and rank.
