✚ Okay, so this would be Erik (name is up to discussion , but for the sake of it, he needed a name for now), a vampire of about 100 years. He's been a traveler around the world all his life. His history, place of birth and life is up for you to decide.
✚ He was in France about three or four years ago, when he met Lyona and transformed her into a vampire. After that, she followed him to NY, where he taught her about her new life, and how to survive, how to hunt and kill. After almost a year, they parted ways, him continuing his travels and Lyona coming to this town.
✚ they shared a bed more than a few time and he's the closest thing to love lyona even had, but it was just fascination she felt; and he took a like in her and her wild personality, the rest of how he feels about her it's up to you. lyona looks at him as a mentor, while he sees her more like his possession, since he created her and wants her to obey him
✚ a few more details about the time they crossed paths can be read in lyona's app
✚ the reason he's in Belgrade now is at your choice and also what he does here (job, etc)
✚ I imagine them having an interesting dynamic, meeting again in Belgrade, even if they made no connection in the last years, him still seeing her as his asset, while she grew even more into her untamed personality.
✚ I imagined his play by being Colin O'Donoghue
or Jonathan Rhys Meyers
, but if you have anyone else in mind, I'm all open to suggestions!
