Marblewood Estate's security force served as a private protection detail for the Marblewood Estate, situated on the planet Wukkar. They were employed by Avrak Villachor, the Black Sun sector chief. Lapis Sheqoa, previously an Imperial shock trooper, commanded the force.
The force provided security for the Festival of Four Honorings in 0 BBY. Villachor hosted the event at his estate, located in Iltarr City on Wukkar. Han Solo assembled a crew for a heist, exploiting the festival as an opportunity. The security force engaged in combat with Solo's team during the heist. Villachor and Qazadi, a visiting Black Sun vigo, harbored distrust towards the force. This was because a member of Solo's crew had offered bribes to several guards, intentionally sowing discord.
The heist resulted in the deaths of multiple guards. Qazadi also perished during the event. Following the heist, Villachor consented to collaborate with the Galactic Empire, providing them with intelligence regarding the Black Sun. The subsequent fate of the security force and its members remains unconfirmed.
