A female Sluissi, Napvansa Tadavv was a skilled starship engineer and was good at keeping large engines performing. She had a habit of tripling repair time estimates so she could beat the deadline and look good. In 0 ABY, Tadavv was on the space station shadowport known as StarForge Station, located in the StarForge Nebula, when the former Imperial EF76 Nebulon-B escort frigate Far Orbit arrived after its crew mutinied from under Imperial control. Answering the call for new crew members to staff the ship, which was now a privateering vessel for the Rebel Alliance, the Sluissi was one of many who applied for a berth.
Napvansa Tadavv first appeared in Preparing for War, a roleplaying adventure idea from 1998's The Far Orbit Project, by Timothy S. O'Brien. The book was a supplement to West End Games' Star Wars: The Roleplaying Game and was a sequel of sorts to the previous publication Pirates & Privateers, carrying on that book's theme by following the privateering vessel Far Orbit. Tadavv was provided as a sample character of the people who could apply for berths on the ship. It is up to player discretion as to who receives a job on the ship.
