Born to a coyote loner, Vesper was raised in Mer Bleue until her father, Marcel Moineau, found and destroyed her family. She roamed as a feral loner, a brat picking fights, until she contracted the Luperci virus through a violent attack. Inferni took in the injured coywolf, and Vesper found her place as a scout, rising through the ranks. She became a subleader under Ezekiel de le Poer and served during the first Boreas Conflict. Following Myrika Tears' ascent to Aquila, Vesper became her subleader and later her mate, raising three children and adopting two more with her.
However, her life in the clan was shaken by several betrayals from comrades and loved ones alike. Her paranoia increased to a breaking point during the Inferni and Cour des Miracles War, when Marlowe de le Poer was revealed to be a traitor. Shortly after exiling Marlowe and ending the war, Vesper usurped her mate and became Aquila -- breaking the several-years tradition that a Lykoi should lead Inferni -- which put her at odds with her daughter Vicira Tears.
The Second Boreas Conflict and a traumatic kidnapping shattered Vesper's already fragile psyche, and she briefly relinquished the role of Inferni's commander to Vicira by necessity. However, the experience brought them closer together -- for a time.
