Assassin's Creed: Cursed (Assassin's Creed Fanfic) Male Assassin Reader x ???

I do not claim ownership of Assassin's Creed, images, or any crossovers that might happen (haven't decided yet) Assassin's Creed is owned by Ubisoft.

The curse to walk the Earth for as long as time goes, a pain casted upon an innocent man that corrupted his mind, a misery given to him by a artifact, simillar to the Staff of Eden but a Dagger, in 76 BCE, Nonus Bursio was, or rather is, a roman man who had his life stripped from him by a artifact giving him eternal life just by touching it. Nonus was later found by a templar named Caecilius Evander in 65 BCE, Will Nonus suffer for ever and be corrupted to be a weapon for the templars or will he become a powerful man that serves the light through the shadow?

I would like to point this out: The events will be the same and genders will be canon, for example Shay Cormac still murdered Arno's Father and Eivor will be female. Enjoy the story of the cursed one!
