A world inspired by Will Wight's Cradle series, featuring a cultivation-based magic system called the Ethereal Arts. The world is divided into ascending elemental realms (Stone, Water, Wind, Fire, etc.), each representing more powerful and rarefied elements. Practitioners cultivate internal energy tied to celestial bodies (Sun, Moon, Stars) and must embody the nature of elements to advance. The world is threatened by the Void Sovereign, a being trying to consume the essence of celestial bodies.
