The Shaper research facility on Dibrook was a hidden Yuuzhan Vong stronghold established on the uninhabitable planet Dibrook some time before the battle there. Master Shaper Nagme led the research facility, and a yammosk was placed under Dibrook's surface to control the Yuuzhan Vong forces on the planet. At the facility Master Shaper Nagme experimented on captured individuals, creating an army of Thralls. Among the captured was a Jedi, Yuledan. In 25 ABY, Commander Tsalok came to interrogate him about another Jedi, Finn Galfridian.
