A/N: Last one! By the way, I resubmitted Part Three. It's different now, go read it.
The daughter of Hecate enters the Underworld.
She wishes that somehow, someway, she could go into darkness.
But it is impossible.
She is not even allowed to go to Asphodel, where her terrible memories will finally be erased.
She goes to Elysium.
She does not think she deserves it, but the judges are adamant.
She wants to switch with her, the best friend she had killed by her actions, but no.
Her friend was in Elysium.
No way could they switch.
So the broken girl recovers with the forgiving smile of her friend in the white light of the ghosts' paradise.
The son of Hephaestus enters the Underworld two months later, granted Elysium.
He is not expecting the way his dead love, the girl that he failed to save looks now.
She is happy.
And now so is he.
So she healed.
They mended each other.
A/N: AND DONE!
