Jenna Zan Arbor's secret laboratory, located in Level One, Quad Two, Block Unit 3 on Simpla-12, was where she did tests on Jedi and other Force-sensitives hoping to find the secret of the Force. Zan Arbor employed a guard named Nil to protect the laboratory. It was abandoned, however, when Obi-Wan Kenobi, Siri Tachi, and Jedi Master Adi Gallia broke in to free Masters Qui-Gon Jinn and Noor R'aya, held prisoner within it by Zan Arbor at the time.
