Eldest daughter of House Arcturus, Vetrise Rodica Arcturus Cardinal. A high sorceress and priestess within Bal Hora. Vetrise left her home behind to study under Sir Vladmir Blair outside Kolonia because of her high intellect and gift for the magik artes. It was also a chance to escape the circumstance surrounding her brother's death that she was unable to resolve.

Naturally withdrawn, Ovara is known to be a shrewd and cold woman, only invested in her research to regain and restore the Penumbra to their former place in the world. the only sentiments she has ever seen to express had been through taking in a disfigured Penumbra child from a refugee squalor. Sorrow became her protegee, but it was a strange connection which led her to the decision.

During the Penumbra Hunts of 165 SE, Ovara rescued Cachusa from the brink of death from an attack, the two reconnecting somewhat as the Penumbra Underground was supported by the Moon Sect of Bal Hora. While Cachusa stunted her sister's growing apathy, Ovara was able to understand the unobservable nature of Cachusa regaining her Penumbra form.

Not much else is known about Ovara aside from rumors; others suggest she and Vladmir had a short-lived relationship while others suggested more, that a child had been bore between them.
