The Windfall was given to Tulsar Leidias as a wedding present by his father. The ship was completely stock when Tulsar received it, but that was soon changed as he and his wife worked on improving the Windfall in every way possible.
One of their very first modifications was the removal of one of the holding cells on the bottom level and the installation of a sparring room where they could practice their lightsaber skills safely. The room is completely lined with a heavy composite armor that resists lightsaber blades. In addition, there are several openings that can dispense remotes, up to 20 at one time.
That all changed upon the arrival of Sivter to Juoi. After Tulsar's wife and son were killed by the Dark Jedi, the Windfall became Tulsar's ship of choice for hunting Sivter down. He improved the armaments and installed a state-of-the-art security system to better assist his hunt.
The Windfall has served Tulsar faithfully over the years and the Jedi considers the ship an extension of himself. It has seen Tulsar safely through several battles, including some big conflicts such as the Battle of Corellia.
The ship serves as a constant reminder to him of his beloved wife and son and why he can never rest until Sivter is finally destroyed.
