The gods, demigods, their friends, and Zóe Nightshade of the Riordanverse are summon to watch a alternative universe. This universe is quite different as it has a certain sword loving Hero of Justice replacing Leo as the son of Hephaestus. Now join them as they watch and react as our heroes join the Great Holy Grail war. (A/n: Cover not mine and this is a both a original and reaction story.)
