"You do know that the institute is in pieces." The words have startled Tessa. She had just landed on the American soil after so many years. Yet, her responsibilities as a Shadowhunter had been calling her once more. Was she ready to protect and love the people she had turned a way from in the past? (ACT II is now being written. For those who still don't know, we do have a part 2)

Tessa quería enseñarles su ciudad natal a Will y a Jem, por eso, con los conocimientos de brujería que había estado adquiriendo, decide hacer un portal hasta allí. Lo que no saben es que, al cruzarlo, no sólo viajarán en el espacio, sino que también en el tiempo. Así es como llegarán al Nueva York de CdS, y conocerán a Clary, Jace, Izzy, Simon, Alec y… al Magnus de la actualidad.

The MI gang tries a Portal to a Clave meeting in London but end up in 1878 after a Magnus style mistake. The MI and ID gangs meet up and have to deal with Mortmain and meeting their distant family members. MI tries to get back to their time. Can the world take the combined sarcasm of Jace and Will? Better than it sounds I promise! Pairings are the same as the books
