Daven Quarle, a Human male, served as an assistant to Imperial governor Parco Ein while the Empire occupied the planet Verkuyl.
Quarle was tasked by Ein with locating an appropriate corporation to construct a bacta refinery, with the aim of bolstering the Imperial war effort against the New Republic. Leveraging his authority to gain influence, he adopted the role of a double agent, feigning allegiance to the resistance in order to undermine the Empire's presence on Verkuyl. During his time working with the resistance, he encountered Selby Jarrad, an agent of New Republic Intelligence. Exploiting her ties with the NRI, he managed to acquire proof of the Republic's plans to dispatch a fleet to liberate Verkuyl. He then betrayed Selby by informing Ein of the fleet's impending arrival. Selby, utilizing her earsculpt listening device, discovered Daven's treachery by eavesdropping on his discussion with the Imperial Governor of the planet. Upon his return, they engaged in a debate regarding the disparities between the Empire's management of Verkuylian BactaCo and the potential future of the company under New Republic governance. Ultimately, he almost convinced Selby to support him and refrain from contacting the approaching New Republic fleet, advocating for continued Imperial control of the planet for the benefit of the workers. Selby changed her mind, however, and fatally shot him using a blaster. Following this, she contacted the New Republic fleet, leading to the planet's liberation by the New Republic.
