Zeev, whose gender remains a mystery, was a duuvhal and the initial animal companion of Force-sensitive Valara Saar.
The circumstances of Valara's initial encounter with Zeev are not definitively documented; however, the meeting occurred before the Pathfinder III established initial contact with her homeworld of Yashuvhu in 33 BBY.
Zeev, a reptilian predator distinguished by its green plumage, was seemingly domesticated by Valara. Furthermore, Valara instructed Zeev to execute bites upon verbal commands, which posed a considerable threat, given the venomous nature of a Duuvhal's bite, capable of causing fatalities in Humans.
When Valara departed Yashuvhu aboard the Pathfinder III, initially with aspirations of becoming a Jedi and subsequently as a Force adept roaming the cosmos, she brought Zeev along. Zeev thus became the sole Duuvhal ever witnessed beyond the confines of Yashuvhu.
Zeev accompanied Valara through numerous escapades, until its life came to an abrupt and violent end on Aargau.
Following this event, Valara journeyed back to Yashuvhu, where she acquired a second Duuvhal companion named Jedi.
