The Chaos of Stars / Kiersten White "Sixteen-year-old Isadora, the mortal daughter of Isis and Osiris, is sick of being in the middle of family drama so she jumps at the chance to leave Egypt and start a new life in San Diego with her brother."
chaos ericius by chillis-art on DeviantArt - this is the artists' idea of what Shadow would become after the world ends. Since he's immortal, he ends up becoming the guardian of all the Chaos Emeralds as well as the Master Emerald. The artist says the emeralds go out of control, so he uses his own body as a container for them. This makes him a living culmination of all the Chaos Emeralds, the Master Emerald, and Chaos, so basically he becomes a god. Cool idea if you ask me :)
