Malec

Malec Malec, (also called Algnus by Simon Lewis) is a canon ship between Alec Lightwood and Magnus Bane in The Mortal Instruments book series.

Canon
Magnus first met Alec in City of Bones when the Shadowhunters of the New York Institute went to the warlock for help in recovering Clary Fray's lost memories. Later in the book, Alec was poisoned by the demon Abbadon, and Hodge Starkweather called Magnus to save the boy. Some days later, Alec showed up at Magnus's apartement to thank the warlock, and wound up asking him out. The two shared their first kiss and began dating, though they were not officially a couple, as Alec was still harboring a crush on his adoptive brother and parabatai Jace Herondale.

Near the end of City of Glass, Alec both admitted his feelings for Magnus and came out to his parents and the rest of the Clave by kissing Magnus in plain sight. The two then lived together until City of Lost Souls, when the vampire Camille Belcourt, who had broken Magnus's heart over a century before, split them up.

After much drama in City of Heavenly Fire, including kidnapping, daddy issues, and a trip to hell, the two finally reconciled and are now living happily ever after.

...And they may even be getting a baby.
