An extraterrestrial civilization invaded Saturn, tearing open the sky screen and creating rifts in the void. Alien species entered Saturn through the rifts in space and time. Spiritual energy from the universe of the void also poured through the opened rifts, causing Saturn's people, plants, and animals to evolve and mutate, gaining superpowers to fight the invaders.
