OK so basically Jace, Clary ( maybe she annoys me) Izzy and Alec maybe Simon meet Nico, Percy, Jason, Leo and Annabeth (maybe Frank) And they clash, each fighting about the clave or the Gods. They have to work together to defeat vampires, demons, minor gods and even some dark angels until they can get to the portal ( where the demigods can transport back home. with no idea wh With no idea why they were suddenly brought into the shadow hunter world Percy wonders if maybe his friends would want to stay.... )
"I'm Nico do Angelo, and its not a pleasure to meet you."
" neither you, you snot nose little ass wipe." Jace hissed.
"Fair enough," Nico grinned. Jace wished he could rip the smirk off his face. Jace blade out to Nico's throat said,
" Now come to me in the name of the angel, or I have permission to cut your heart out." Nico grinned.
"I was hoping you would say so etching like that." he laughed as the ground began to shake. Jace stumbled back thinking it was a warlock, it had to be. That's when skeleton hands broke threw the earth and began to the surface. No, not a warlock Jace decided, something, much, much worse.
