Percy Achilles Jackson: demi-god and whitelighter

1

Perseus Achilles Jackson, two time Savior and Hero of Olympus had been betrayed by the entirety of Camp Olympus for his new brother Adam Briggs.
Accused of things he did not do, but the annoying part of the whole thing was that according to Zeus his power levels were above that of a normal demi-god, so using his veto power as King he banished Perseus from Olympus, Atlantis and Camp Olympus; so he left deciding to go off on his own. Another thing he did was not involve his mother or his father(he had begged Poseidon not to oppose Zeus and start a war over his banishment). He had partial immortality thanks to Artemis discreetly giving it to me without Zeus knowing but later the Fates caught up with him and upgraded it to full immortality granting him his father's domains amongst others:

Watching this was Hecate, she knew he would come to straight to her to help him in hiding his new nature from the rest of the Olympians, he had brought her respect by giving her as the other Minor gods seats on the Olympian council, so she would help him.

While Hecate was not respected by the Olympians because she was a Minor goddess, alternatively she was respected by mortals as the Charmed One Prudence Halliwell. Her supposed death was actually her shedding her mortal form to return to Olympus after Percy had restored her prestige, she hated lying to her beloved sisters but sadly it was the Olympian policy that she could never reveal her heritage as a goddess; hence her "death" was the only way out
Now Perseus had been cast out, Leo was held up being an elder(in this case Leo does not fall but was permitted to save his child) and Wyatt had been returned to the future after the Gideon fiasco.
Thus Percy Jackson was the perfect candidate to protect her sisters until Leo was allowed to return.

You see she offered him a chance to partially leave the world of the gods behind by going to San Francisco, there he met the Halliwell sisters Piper, Phoebe and Paige a.k.a The Charmed Ones
He helped them vanquish a Minotaur summoned by Cole who had become an infernal one(their on and off enemy and occasional ally) to capture Phoebe who he intended on making his Queen once and for all.
Then the unexpected happens, the Fates appearing there after the incident, reveal that Percy's mother Sally Jackson as well as being a clear-sighted mortal was also a former white lighter, furthermore, Percy Jackson her dear son while being a demi-god son of Poseidon had his mother's second gift passed down to him.
In other words, he was a demi-god and a White lighter
