"The trident must be reformed. Brothers mend what is torn. Together all the world's are saved. Apart the darkness has its way." A new prophecy comes to light. Perseus Jackson is not the only Hero born to the sea god. In fact he is not the only son of Sally Jackson and Poseidon. The prophecy brings the brothers together but can they save their worlds or will sibling rivalry end life as they know it? This is a crossover with Percy Jackson, Harry Potter, and Spider-Man... well by the end of it many more Fandoms will be represented but those are the "big three" (Percy Jackson Pun intended)
