Before she became a part of Armand's first Parisian coven, Allesandra was part of Santino's satanic coven (the coven that took the immortal Armand from Marius). With tangled and filthy grey hair, and clothed in antique rags, Allesandra questioned Armand on "Those Who Must Be Kept".

Given the Dark Gift in the forests of France, and older than Santino, Allesandra went to Paris with Armand to lead an abandoned coven. She gave Armand his current name (previously Amadeo).

Clothed as an ancient queen might have been (to use Lestat's words) and older than Magnus (she was part of the coven from which Magnus stole the dark gift), the "queen vampire" exhibited a degree of lunacy and claims that predictions she has made have all come true upon Lestat and Gabrielle's capture by the coven.

Often by Armand's side, the "queen vampire" encourages Lestat and Gabrielle in their protests against the coven, and accepts the couple, saying she will never harm them. She commenced the destruction of Armand's coven by jumping into the fire to join Magnus (to use her words).
