Drifting through the cosmos, Sol - the elemental titan of light - and Azure - the elemental titan of darkness - have been engaged in combat since time began. The gods contained them within a stadium where they could witness these celestial titans. This stadium is Arcadia, a ring-shaped planet surrounding the conflict.
The lives of the mortals that inhabit this ring are dictated by the titans. Day turns to night and night into day, depending on who has the upper hand in the celestial combat.
And so the world watches the Titans carefully, dreading the day a victor emerges.
