Talulah is the daughter of Edward Artorius, a close friend of Wei Yenwu and scion of royal Draco bloodline in Victoria, who fled the country in order to avoid the persecution of the Aslan house.

Before she was born, Duke Kashchey of Ursus secretly orchestrated a scheme that led to Wei to kill her father under the order of Wei's younger twin brother, the current Emperor of Yan. In order to protect his sister from his jealous brother, Wei arranged another marriage to Ch'en's father. Such decision would cause Ch'en, Talulah, and their mother to detest him. Due to the circumstances of Edward's death, Wei could not bring himself to love Talulah either. Talulah escaped the city due to feeling isolated.

Since then, Kashchey had been raising her as his heir to be the next "Deathless Black Snake." He had her study the history of the Ursus Empire, tried to teach her his ways, and promoted her to be his agent in order to carry out the will of Ursus. Even then, Talulah frequently dismissed Kashchey's attempts to "educate" her; she continued to reaffirm her own ideas as she saw the state of Ursus with her own eyes, such as the suffering and persecution of the countless Infected. To foil Kashchey's plans for her, she purposefully contracted Oripathy with an Originium ore embedded into her arm. Seeing it doesn't deter Kashchey, Talulah then decided to end their feud once and for all by killing him. Unbeknownst to her, it only allows Kashchey's consciousness to be passed onto her through his psychic Originium Arts.

Years later. Fire, fire is all you can see around yourself, the whole of the control tower set ablaze, but you have to stop the city of Chernobog from colliding with Lungmen. And before you... is the Deathless Black Snake, longsword in hand, cold, unfeeling eyes. It's not Talulah. Save the cities, save everyone... and save Talulah. Wordlessly, her sister Ch'en, who stood by your side, understood you.

— The last person in this city who could kill me is now dead. Now I have nothing left to worry about.
