History
It was unclear when their homeworld was discovered by the Hutts but they were seen in many parts of the galaxy by 10,000 BBY. In the Clone Wars many Rhiongophund ships were seen fighting for the Confederacy of Independent Systems but the size of the species meant they were never among ground forces. The Galactic Empire deported most of them from its worlds and a secret genocide was carried out against those who remained in Imperial space. By 4 ABY, almost no Rhiongophund lived outside of Hutt Space. After the Yuuzhan Vong War further decimated their population, there were less than a few thousand in the whole galaxy and by 100 ABY they had gone extinct.
