Backstory : "Marion no ! » the reverberation of her voice in her coffin woke up Selena Vitalli. Always the same nightmare, the moment when the darkness came inside her heart. The loss of her partner and the fall of the Hall of Vigilants, all these thoughts continued to haunt her. She felt so weak, without a goal nor hope. Joining the Dawnguard seemed to be a good option; a suicide mission. All that changed when she met Serana, awoken from her long slumber. She gave off strength and charisma beyond her imagination. Becoming a vampire after hunting them for so long why not after all, she had nothing to lose. She embrace this un-life with all her will finding a thirst she never knew. The taste of the blood invigorated Selena's undead body. The life she took warmed her being giving her more strength . The gifts of Lord Harkon were great but even he was nothing compared to her new god. She swore to become his most faithfull servant; The Vigil of Molag Bal.
