Legacy of Olympus

Warning: Heroes of Olympus and Harry Potter crossover. And the demigods will be undercover. But the first few chapters revolve around a new character, Emma Macbeth, A.K.A. Legacy of Olympus.

Emma Macbeth is a student at Hogwarts School of Witchcraft and Wizardry. She specializes in wandless elemental magic (Water, Shadows, Light, Wind, Lightning, Earth), physical combat, and making plans. She is a troublemaker and stealthy, but she is wise enough to know that she shouldn't do anything too stupid.

Her parents despise her because they are jealous that she partially has the powers of all the Major Gods and Hecate. What she doesn't realize that she has hidden power inside her, which is a mix of all the powers she has.

Back at Camp Half-blood, Rachel spouts a new prophecy.

After the Battle of Hogwarts, everyone that was in 7th year but their year got, well, ruined, gets to go back. The Gods think this is a chance to see Emma and decide what to do with her.

The demigods go to Hogwarts undercover to find out about Emma and also prevent the rise of the primordials.

Meanwhile, the Golden Trio is suspicious of what will happen...
