Dree Vandap was a young Rodian female serviced herself to the Jedi Order during the time the Jedi Army of Light was battling the Sith Brotherhood of Darkness. Apprenticed to Jedi Knight Crian Maru and undertook the mission of tracking down one of the Brotherhood of Darkness' most ferocious warriors, Kaox Krul, the Madman, the Marauder, the Dark Killer. Traveling to the Balowa system to the planet Harpori, Dree and her Master believed they had a lock on Krul. However, the Marauder was able to get the jump on Dree and Crian and blasted their ship, damaging it beyond repair and sending it on a doomsday decline to the forested planet below. But, Dree and her Master were also able to damage Krul's ship sending it plunging to the planet as well.
Luckily, Dree and her master survived the crash, but were now at the mercy of the planet's elements, and also, at the mercy of Kaox Krul who had survived his landing as well. Dree and Crian surmised that they needed to put some forest between them and the Madman so as to keep ahead of them. However, as Crian was preparing the ship's speeder bike that had survived the crash, Krul was upon them. Dree was forced to engage him in battle but was rescued by Crian who snatched Dree up onto the bike as she sped past the fray. Zooming into the forest, the two Jedi thought the bike would help them put some distance between them and Krul.
However, Krul opened himself up to the power of the Dark Side, using it to give him incredible speed allowing him to keep up with the bike. Slashing out with his lightsaber, Krul cut cable lines causing the bike to slowly lose power. However, Krul's swipe also caused him to lose his footing, sending him crashing into the ground and allowing Dree and Crian to escape, at least for the moment. For two days afterwards, Dree and Crian were able to elude Krul, but eventually he caught up with them. The showdown came one night when Dree awoke alone in a makeshift hideaway in a forest cave. Following her senses to a lake located in the middle of the forest, Dree found her Master standing at the shore. Without warning, Krul appeared and attacked Dree's Master.
