Anima's Encantation of Primordial Genesis

For 24 hours straight, you concentrate on the material components before you, gesturing and chanting all the while. At the end, roll 1d100. On 01-25 you die, and the ritual continues beyond your control, consuming the material plane in favor of a new design. Should you survive, the spell is completed as intended, and an alternate material plane of your design is created in the early stages of its life cycle, still consumed by primordial elements. It will reach a suitable, but primitive, state in 1d100 X 1000 years. You gain three points of exhaustion. If you ever attempt to cast this spell a second time, your spirit shatters and your body will turn to dust, killing you instantly.
