Here's what I've found that was suitable (this is not an exhaustive search)

Dirha (grid s-9) was a gritty industrial planet^[4] that was located within the Dirha system of the galaxy's Hutt Space region^[1] and lay on the hyperlane^[2]called the Sisar Run,^[3] which connected it to the world of Cyborrea^[2]and the Sespe system.^[3] Dirha lay within the sphere of influence of theVosadii kajidic, a clan of the Hutt species,^[6] and served as a refuelingpoint for starships that traveled along the hyperlane toward the planets ofNimban and Nar Kreeta.^[4] After the military forces of the extra-galacticYuuzhan Vong species invaded the Hutt Space, Dirha was terraformedby members of the species^[4] between 25 ABY and 29 ABY^[5] in a process called Vongforming.^[4]

Diyu (grid s-12) was a planet^[4] that was located within the Diyu system of the galaxy's Hutt Space region^[1] and lay on the hyperlane called theShag Pabol, which connected it to the Rorak system and the world ofYlesia.^[2] Diyu was a major industrial center that relied on slave labor for centuries.^[5] The Anjiliac kajidic, a clan of the Hutt species, had influence on the planet.^[3] When the military forces of the extra-galactic Yuuzhan Vong species invaded Hutt Space, Diyu escaped their advance.^[4]

Rorak 4 (grid s-12) was an industrial planet that was located within the galaxy'sHutt Space region and lay on the hyperlanes called the Gamor Run and the Shag Pabol. Rorak 4 was orbited by the Rorak 5 space station and was the site of the largest slave market in the Hutt Space.

Rorak 4 was an industrial world^[3] that was located within the Rorak system of the galaxy's Hutt Space region^[1] and lay on the hyperlanecalled the Shag Pabol, which connected it to the planets of Nal Hutta andDiyu. Another hyperspace route called the Gamor Run linked Rorak 4 to the world of Circumtore.^[2] Rorak 4 was orbited by the Rorak 5 space station and was the site of the largest slave market in the Hutt Space.^[3]

The Rorak system was located within the territory controlled by the Huttspecies at least as early as the year 11,000 BBY.^[5] and the area of space surrounding the planet was considered well-explored by 8000 BBY.^[6] The local population average of the region of space containing Rorak 4 around the year 25 ABY ranged from 10 million to 500 million.^[4]At some point between 26 ABY and 27 ABY the Rorak system wasattacked by the military forces of the extra-galactic Yuuzhan Vongspecies during their conquest of the galaxy,^[7] and the star system was held under the control of those invaders until at least 27 ABY.^[8]

Hollastin (grid s-12) was a minor trade world located in Hutt Space, serving as a clearinghouse for goods from other outside regions. It grew greater in importance after the Yuuzhan Vong War as a result of remaining untouched by the invaders.

I'm thinking of using Diyu and making Grondo part of the Anjiliac clan
