Hogwarts

What happens when worlds collide, we are about to find out. When Percy Jackson accidentally stumbles through a portal he suddenly finds himself in front of a large castle like structure and children wandering around in robes and holding wands.

When Albus Severus Potter, first year at Hogwarts (school of witch craft and wizardry) finds Perseus Jackson he is not sure what to think. He only has a feeling the this boy doesn't belong here. What they don't know is just how much damage is being caused. The colliding of the two separate worlds is causing the magical barrier that keeps them apart to collapse. And with it, Hogwarts and Camp Half-Blood.
