Main relationship: Magnus Bane/Alec Lightwood
Thrown out by his parents and forbidden from seeing his siblings, when Alec’s grandfather Andrew passes, he loses the only family he has left. One night Alec receives a mysterious package in the mail, his birthright from Andrew whose death left Alec alone in the world. Inside, he discovers his family secret: the firstborn Lightwood of every other generation has wings.
With the knowledge of how to unlock his wings, Alec takes to the skies over New York every night, as a way to escape the sadness of his life. One night, he sees a man far too drunk to be standing that close to a railing and catches him just in time.
So starts a tentative relationship between the ‘broken’ Magnus Bane and his guardian angel who appears on his penthouse balcony every night. Together the two start to heal on their own and as a pair.
