Percy Teaches At Hogwarts

DISCLAIMER: ALL CREDIT GOES TO: RICK RIORDAN AND J.K ROWLING!!! Sadly their not mine... ;(
Everyone Percy loved died in the war, and Percy was left all alone. His Heart and Soul was broken like shattered glass beyond repair. And he is stuck with major survivors guilt. All of the deaths, Jason, Piper, Leo, Hazel, Nico, Thalia, Frank, and his Wise Girl, Annabeth. All of them, dead. The Gods made gave him their blessings and made him immortal. But stronger than any minor god. He was made an Ultima God. Stronger than any Olympian. Heck, even Chaos came down to reward him. Why would they reward a monster? Was Percy's thought. He could have saved everyone, but he didn't because he wasn't fast enough, strong enough, good enough. He was made the Ultima God of Heroes, Loyalty, Guilt, Elements, Swords and Magic. His sacred animal is the Pegasus, and the Wolf. He has two because his father is kinda the god of horses so...
He is sent to a school called Hogwarts for Witches and Wizards to teach students, and protect a guy named Harry Potter, a boy who has a ego bigger than Zeus, *Thunder Rumbles*
C'mon you know it's true. But war is coming up, and Percy must protect them, he can't lose the people he was meant to protect, not again...
