do you know who turned Felix and Demetri? Why did they became a part of the Volturi do we have any information? I really wanna know
To answer your question, I only know Demetri's story. He was turned by Amun (who is part of the Egyptian coven) around 1000's AD (I think, google to the rescue😅). Im not exactly sure how long metri was part of the Egyptian coven but it had to be long enough for Amun to be able to help him be able to master his tracking gift. Obviously Demetri did not just willingly join the Volturi, Aro being the power hungry vampire he is had Chelsea manipulate his emotional bonds so he would join the Volturi easily. As since then he has been part of the Volturi.
As for Felix, not much is known about him which sucks but at the same time it gives room to be creative with his backstory. All that is really known about him is he was turned by Aro. I remember a while ago I read a post about Felix in how and why he was turned. It said that the kings along with the wives went to the Colosseum to see the gladiators and supposedly Athenodora was the one who saw potential in Felix. Again they probably used Chelsea again so he would stay with the Volturi forever and not dare leave. You can fight me all you want but I will always say that Felix was a gladiator in his human years, he is known for his battle strategies and combat skills, he might not have a gift like Demetri or the twins but he is still is a prized fighter.
Overall, they both didnt really have a choice in joining the Volturi, it was forced and manipulation that got them here and yet we adore them to death. I hope that answers your question dear😁.
