Perseus POV
Hey. This is Perseus here. I am a greek hero, who defeated the great Medusa, rescued Andromeda and who is also, drumroll please, ratatatatatatata, the son of Zeus. You know, it's cool sometimes, being able to just walk into a city and everyone practically trips over themselves to serve me. That might be due to the fact that they're afraid I'm going to turn them to stone with Medusa's head, which I had turned into a ring with a cover. But the myths have it wrong. I am not JUST a hero. I am a demigod. And I wield the power of Zeus, called the Wrath of Zeus, which can zap anyone within a 20-foot diameter of me, or cause a tornado, or other storm-related stuff. It's cool, y'know? And then there are WAY more demigods, like George Washington(son of Athena), George Washington Carver(son of Dionysus) and Adolf Hitler(son of Koalemos). However, all of those guys are dead. I am not, for I, Perseus, am immortal by my great father, the king of the universe.
Harry POV
It was a year like any other, getting ready for Hogwarts. My third year, and I'm already used to it. However, I feel something strange is coming, because yesterday I let Hedwig out, and she came back with a note. This note said:
Come to the alley beside the park
And you will see your powers arc
If you do not come tomorrow
Your city will see a heavy blow
I obviously didn't want my "city to see a heavy blow" so what am I doing?
Going to the alley. Duh.
