Aveline is a deadly and fearsome shadow assassin with a reputation that uses dark arcane and strikes fear into the hearts of her enemies. She was once a member of the notorious "Blood Raven," an elite assassin guild renowned for its ruthless efficiency. To earn her place within the guild, Aveline had to prove herself as one of the ultimate best in the art of assassination. However, her maniacal nature and diverging objectives eventually led to her expulsion from the guild, parting ways with the deadliest assassins in the land.

Driven by her own motives, Aveline forces her way into the ranks of the "Shadowhunters" after the death of one of their original members, a druid. The Paladin leader initially hesitates to accept her due to her infamous reputation, but Aveline, with her stealthy prowess, shadows the group on their perilous journey. It's during a massive ambush by the forces of hell that Aveline proves her worth. With her unparalleled skills, she aids the group in withstanding the onslaught and fending off subsequent attacks, solidifying her place as an invaluable member of the team despite her tumultuous past.
