Summary
Winter Solstice has passed—and the prophecy remains unfulfilled.
But peace is short-lived. The Next Generation of the LBAF faces greater trials than ever before.
Lance wrestles with the true nature of his powers. Arthur fears that death is just around the corner. Joan is given a task she feels utterly unprepared for. Kincaid faces the heartbreak of losing the one he loves. Cami risks her shot at becoming Consul. Iris falls for someone she doesn't think she can have. Atlas uncovers long-lost secrets he wasn't prepared for. Règine is torn between loyalty and betrayal. And Arjun dreads being left behind again.
While the young heroes navigate love, loss, and legacy, Lucifer quietly advances his master plan, with Madeleine, Asmodeus, and Mikkel each plotting their own deadly revenge.
Can Alec, Magnus, Rafael, and Max survive the storm—this time, together—or will the weight of their demons finally tear them apart?
And above all...what about the Other Magnus?
Let’s find out.

Summary
Clary Fray is a fighter, or at least she has been ever since that night. The night that changed everything. Her life was almost taken out from under her but rather than let fear take control, she uses it to fuel her lust for revenge. She joins the Shadows of the Night, which is one of the two best fight clubs in NY. She has a plan: Be the best, never lose, feel nothing, and never go back to the girl she used to be. But what happens when the one man that can make her feel alive again turns out to not only be her rival, but the leader of Legends of the fall? Jace Wayland is the worst possible person Clary Fray could fall for but that doesn't stop her from tumbling into that golden abyss.

Summary

Alec had considered many different possibilities about who his roommate would be: if they’d get along, if the person would be awful. However, he had not prepared for this. He hadn’t considered the possibility that his roommate would be a sculpture hand-carved by God himself sent to torture Alec specifically.

Summary
Cyrus is just a human boy. A random, silly, dumb teenager, lost in a sea of sweaty dancing bodies, easy and accessible prey.
Therefore, however, he... ceased to be.
More specifically, he ceased being just a human boy (He's still silly, dumb, easy, acessible and a prey).
Or
It is an original story BASED on the premise of Simon Lewis and Raphael Santiago's ShadowHunters | Mortal Instruments.
The original characters from the series will not appear, they do not exist in this universe, but I may occasionally use nuances of their plot.The focus here is the Sire/Fledgling relationship between Cyrus and Edgar, which you'll find is quite similar to Raphael and Simon, but with my own gentle twist.
Yes, this will develop into a romance in due time.
