Nina I have to tell you this. I like you, and I know it sounds like it's coming from out of no where and that I kinda dated your sister but I do like you. Since the last time I saw you and talked with you I've been growing a crush on you. I know it's not the best time to tell you this but I couldn't leave without saying it to you. I wanted to get it off my chest. Now you know.

Early History[]

Roman and his human family were attacked by werewolves; all died but Roman who was found and taken in by Greta Sienna. In 1933, Roman and his adoptive family were in Germany and encountered Klaus. Klaus ripped out Roman's father, August's, heart and slaughtered most of his village before giving mercy to Roman and his mother, Greta, and sister, Antoinette. This encounter shamed their family and caused them to create a cult that believes in the true nature and purity of vampirism.

After August's death, Roman spent 50 years trapped in a cave, desiccated, before Greta found him.

Some point prior to 2026 Roman enrolled in the Salvatore Boarding School for the Young & Gifted, per Greta's instruction, to follow Hope Mikaelson, Jaxon Salvatore, Nikolina Gilbert-Salvatore, and Lillian Gilbert-Salvatore.
