Summary
“You two know each other.” It was more of a “I’d known already, but I wanted you to say it to my face” than a question.
“Old acquaintances,” dismissed Alec.
“Not what I would go for.” Magnus sounded rather unimpressed. He turned his head to Alec’s partner, gold-green eyes filled with exasperation. “But whatever Alec wants, Alec gets, am I right?” He reached out a hand to Rex, and it didn’t hold the same weight as he usually did. “Magnus Bane, High Warlock of Brooklyn, at your service.”

Summary
“Alexander,” Magnus said with an exasperated tone, the same as the night he first said he loved Alec. “You don’t have to avoid me like I’m some sort of bubonic plague. We’re adults, we can be civil with each other.”
“Yeah.” Alec nodded. Maybe this wouldn’t be the first time Magnus extended an olive branch to his exes. Magnus’s always been kind and patient, even to people who didn’t deserve it, like Alec’s pathetic self. He could try to reciprocate the gesture for Magnus, too. “So, friends?”

With the help of the usual found family gang, these Shadowhunters journey towards "I do" with a trip to Kleinfeld's (ft. THE Randy Fenoli), disagreements about bridesmaids dresses, a very mushy ceremony, and the cutest ring bearers in the world.

Summary
After everything they've been through--including war, demon possessions, a literal trip to hell, and some really bad parenting--Clary, Jace, Simon, Isabelle, Alec, and Magnus venture into a life of domesticity, but things persist as usual: Jace acts rashly, Isabelle keeps trying to cook something edible, and Magnus tries out new nicknames on an ever-unimpressed Alec. But actions have consequences, and when Clary and Jace end up starting a family sooner than expected (always use a condom, kids!), the gang is thrust into baby showers, wedding planning, and the future they never thought they'd have.
It's all silly fluff with our favorite cast of Downworlders, Shadowhunters, and whatever Simon is.

Summary
He'd never wanted to be a father before, he knew that warlocks couldn't, but lately it was something he couldn't stop wanting to live next to Alexander.
When Clary becomes pregnant with a special baby, Magnus is her only way out to save them all. But... What is the price of that favour? How much do they have to give up? What changes will this bring to everyone's lives? To Magnus and Alec's lives?
-the characters (at least most of them) are not mine, but Cassandra Clare's, author of those magnificent books that have obsessed me.
- the fanfic is basically from the books, although I took the liberty of taking some characters from the series and accepting some changes that were made in the series, all this with the purpose of making the story better.
- however, the characters in the fanfic are based on the descriptions in the books. -

Summary
Simon sat on the edge of the rooftop, dangling his feet over the edge. He didn’t know why he was here, but this random apartment building brought him peace and familiarity, even though he didn’t remember ever coming here. He contemplated the loose ends of memory he had: A girlfriend, fangs, fearing the sun, angels, werewolves, a mentor dying. Nothing made sense. Where was this girlfriend now? Why would he fear the sun? How did his mentor die? He heard footsteps and turned, ready to fight, when he saw that it was just his sister.
Or...
I finished TMI and refuse to believe that Simon lost his memories forever
