Depends where they take the story.
- Alleria = Lady Sun (we lack a sun magic force thing) = Void
- Sylvanas = Lady Moon (Elune gesture) = Death
- Veressa = Little Moon (self referential to Sylvanas, but also Blue Child) = Order (via Dalaran affiliation)
That leaves.
- Lirath = Little Sun (WEIRDLY SIMILAR TO LITTLE LION HUH) = ??
