Fraid in DC
Danny's life had been going well, his parents had accepted his Ghost Half, Dash is less of an asshole and is trying to better himself, same for Vlad, and Dan had reformed! That's when things began to go south. The world around Danny began to crumble around him and the Halfa tried to save as many people as he could.
He could only save three people... Jazz, Dash and Wes... he tried to save others... they were killed before he could even reach them. And when Danny found out that the Observants were the cause of his world being destroyed? He attacked them, nearly wiped them out, it took the might of Dan, Dani and Vlad to hold him back and get him back to his senses.
Vlad was trusted to be Regent while Danny grows up, as he is too young to inherit the Throne of the Ghost King, Clockwork even found a dimension that Danny, Dani, Jazz, Dash and Wes could live in, it's similar enough to theirs that they wouldn't destabilize the dimension by being in it.
Dan remains with Vlad to protect him, while Fright Knight goes with Danny to protect him. They were set up with a good apartment to live in which is located in a city called Gotham, as it's the only city they have learned that allows minors to live in the apartment if their adult guardian(s) give the information themselves.
All four of them are going to Gotham University, paid for with Danny's fortune he inherited with the Ghost King title. Jazz is in Psychology, Danny is in Aerospace, Engineering and Programming, Programming because he wants to remember Tucker in a way, he'salso got the smarts for it, he even helps take care of plants to remember Sam, Dash is obviously going for a sports major, and Wes is living in Gotham, but going to Metropolis for his journalism.
Things have been going well, but there are people snooping around them, they don't know it, but Danny is an Alternate Jason, Dash is an Alternate Oliver Queen, Wes is an Alternate Wally, and Jazz is an Alternate Barbara, and Danny knows that the Heroes are snooping around them, because he can feel them entering his temporary Haunt.
