Until the Lurians and the Enweili make their proper multi-realm empires, at least. Mind you, I don't think BT will survive long enough to ever see the Holy Enweili Empire rise.
Yes, but Dwilight just might last long enough for the Lurians to pull it off. Unfortunately, the only one who has tried is hated by most of her realm, and everyone else is too power hungry to let a multi-realm empire be established.
