In the wizarding world, Harry, Ron and Hermione are invited back for their seventh year at Hogwarts. The war has left a huge impact on everyone, and the three are hoping to be able to relax and enjoy their final year at school. But honestly, fate just has to- [better not finish that sentence. After all, the Three Fates can get very touchy...] At Camp Half-Blood and Camp Jupiter, another quest has been issued, and much to the complaints of everyone, the Seven, Thalia and Nico are sent to Hogwarts. They soon find out that there is no time to enjoy themselves, though, because something primordial, something ancient and powerful is stirring, and it is stirring awake... "Nine half-bloods roam the sorcerers' land." "Child of the dead halts second chance." "Join the fates of worlds beyond," "Who unite to battle the bane of bonds."

After the war with Gaia, the seven, Reyna, Calypso, Nico and Thalia are sent on a quest to Great Britain, to go to Hogwarts, a School of Witchcraft and Wizardary in Britain to learn the ways of the forgotten wizarding world. On their quest, they will make friends and enemies amongst the students at Hogwarts. However, one question remains above all others. Will they be able to make an alliance between the two worlds, or will a raging war erupt between them? DISCLAIMER: I DO NOT OWN ANY OF THE CHARACTERS IN THIS STORY, I ONLY OWN THE PLOT!
