Viviana Petrova/1473-1490s

Viviana Petrova (Cyrillic: Вивиана Петрова) was born, along side older her twin sister Katerina Petrova into a noble and wealthy Bulgarian family on June 5, 1473. Vivienne developed her powers of being a seer at a young age. It started with knowing things before it happened. She told her mother about it but her mother told her to ignore it and she did. This eventually turned into headaches then her premonitions started occurring in her dreams. At the age of 11 she started getting premonitions of Klaus. She would get glimpse of his past and his future. In 1490, when they were about 16 or 17 years of age, her sister Katerina became pregnant by an unknown man, a Traveler, and her family disowned her for the shameful birth of an illegitimate daughter. Seconds after Katerina's daughter's birth, she was disowned. Viviana not wanting to abandon her sister, she stood by her and left with her and the two fled to England where they 'quickly became English.'

In 1492, Trevor invited Katherine to Klaus's birthday party. She brought her sister along, at the party, Vivienne meets Lord Niklaus. She is blasted with past premonitions from when she was a child of Klaus. Releasing it was him along she says 'It's you'. Vivienne and Katherine are invited to stay with Klaus and Elijah. When staying with the Mikaelsons, Vivienne fell in love with Klaus. He thought her how to control her visions and helped train her with receiving them by will. Upon overhearing a conversation between the brothers, she found out Klaus was planning on using her and Katerina as a sacrifice to break the Hybrid Curse placed on him.

Vivienne puts Klaus in a vision long enough so her and her sister can flee. They escaped with the help of Trevor, who had fallen in love with Katerina. He told them to go east to a cottage in the woods where they would be safe. When they arrived at the cottage, Viviana and Katerina met a vampire named Rose. When Rose found out that the sisters had escaped from Klaus with the moonstone, she locked them in a room and told them that she would take them back to Klaus as soon as the opportunity arose, not wanting to suffer Klaus' wrath. Viviana told Katerina to stab herself with a knife, when she asked why she told her sister she had a plan. After Katerina stabbed herself, Viviana slit her wrists with the knife and this act made Rose feed them her blood to heal. When Rose turned her back to confront Trevor, both Viviana and Katerina hung themselves with a length of rope. Later, when Viviana woke up in transition, Trevor asked why she did it and claimed he would have helped her and her sister live. She told him she saw what would happen, running was never going to be enough. Knowing that Klaus would find their role in the escape, Rose attempted to kill the girls with a stake but Viviana was too quick and used the owner of the cabin as a shield, which resulted in her dead. She gave into instincts and drained the old lady, completing the transition into a vampire before she grabbed her sister and they both fled into the night. Viviana returned to Bulgaria in the later months of 1492 to find her entire family brutally slaughtered by Klaus. She knew he had done it as revenge for her and Katerina's escape and subsequent transition.
