Siobhan was born in 1870 into a wealthy family in Dublin. Assigned male at birth, she was the second child of the family and therefore not destined to inherit the family estate.
From a young age, Siobhan entered the clergy and became a monk in a monastery near Dublin. She lived a life governed by religious rules, but in her heart lay dark sins. Her trans identity was a burden to her, a curse. She hid her true self in the shadows, fearing the societal repercussions of the time.
Siobhan punished herself for her "impure soul," practicing self-flagellation, but no lash could cleanse what she truly was.
So, in her room at night, she would dress in women’s clothing, dance, and live as her true self—all hidden in the shadows of the monastery.
One day, a man appeared: Father Sullivan, who came to visit the monastery. From the moment he arrived, Siobhan’s life became a nightmare. The shadows she once hid in began to whisper to her, tormenting her with terrible visions—hallucinations that tortured her each night.
She tried to speak to the other monks about it, but they concluded she was being punished by God, her suffering the result of her sinful nature.
Hell continued for weeks until one evening, Father Sullivan opened her door—accompanied by other monks—to reveal the truth about Siobhan and her habit of dressing as a woman.
The young monk was banished from the monastery in the dead of night. She fled, lost in the wilderness. Father Sullivan came to her, emerging from the darkness of the night to forcefully embrace her. He saw in her a purity within darkness, a tortured soul that made the shadows her home.
Father Sullivan disappeared, leaving Siobhan for dead in the wild. But she returned to life a few hours later—starving, her mind clouded. She made her way back to Dublin, where she found the family home. That night, she slaughtered her family, blinded by a damned thirst.
When the carnage ended and her thirst was quenched, Siobhan came to her senses. Realizing her damned nature, she was overcome with grief. Fallen and cursed, she had become a vampire—a creature of the devil.
Father Sullivan found her a few nights later and took her under his wing. They left for the United States and joined the ranks of the Sabbat, committing all manner of atrocities.
In Los Angeles, Siobhan met a vampire named Drolta, a Tzimisce who agreed to reshape her body. Siobhan made a pact with her, and Drolta gave her the body of her dreams. But she didn’t know that Drolta had carved a magical sigil into her back, binding her to her will.
Later, Siobhan left the Sabbat, killing her sire in exchange for acceptance into the local Camarilla.
But Siobhan did more than just kill her sire—she committed the unthinkable: diablerie, the ultimate vengeance for the fate he had imposed upon her.
Today, Siobhan is the Lasombra Primogen of Los Angeles. She runs a nightclub and is accompanied by a werewolf bodyguard.
