The Château Malreaux, situated on the planet Vjun, served as the age-old residence for the Malreaux family. This somber structure, painted in hues reminiscent of dried blood and spoiled milk, presented a cream-and-crimson facade and stood guard over the Bay of Tears. Boasting state-of-the-art security measures and a network of concealed passageways, it ranked among the most impregnable sites on Vjun. The late Viscount Malreaux, amidst his slide into insanity and extreme distrust, commissioned the installation of this security network.
This security network incorporated a variety of automated traps and defensive laser emplacements. Furthermore, the Château possessed advanced shield generators, thought to have been disabled by Count Dooku upon his arrival and subsequent occupation.
During the Clone Wars, Dooku utilized the Château as a component of a trap designed for Yoda. He summoned the Jedi Master under the pretense of discussing his return to the Jedi Order; however, the mission ultimately revealed itself as a deception.
