In the moment, life was good. All worshipped him, for they were his kingdom.
Too bad it crumbled beneath him.
It started with the revolution. He got demigods to stand behind him, or more accurately, Kronos. That was the founding.
But the place he got his tools from was the hatred for his father. He was never there for him, so he looked for people who would be.
The first battle on the ship helped him with future planning. Even though he was defeated by the upstart, he made sure to get more powerful before facing him again.
In the fall, he doesn't remember the exact date, he visited the Styx. But not before visiting his mother. It brought up awful childhood memories. But at least he became more powerful.
When he battled Thalia at Mt. Orthys, he tried his hardest to suppress his memories of her. All of the good memories of her, Annabeth, and him on the road fighting monsters, they had to leave.
His future subjects were depending on him.
And when his new soul was finally installed, the stupid mortal just had to mess up the ritual, didn't she?
At least he got to show up Percy again, right?
But the final foundation fell when Annabeth destroyed his will by throwing that broken promise in his face. She might as well have just stabbed him with her dagger, or with those big, sad, grey eyes.
And with the end of him, was the end of his kingdom.
But maybe that wasn't so bad anymore. Maybe, just maybe, he would be fine, even okay in Hades.
As long as his family, his real kingdom, was okay, he'd be fine.
