The Shadowbinder and the Lightweaver actually have a close relationship as far as Gods go. They realized a long time ago that their respective elements basically mean nothing without the other. The nature of their relationship often shifts from friends (with and without benefits), to sisters, to lovers. Their “rivalry” is basically just an elaborate series of games to help them stay at the top of their game. Dominance battles between their two flights are contests to see who tops during sex.
