Arapia, situated within the Arapia system, served as the adopted homeworld for the Kadri'Ra.
In the era of the Galactic Republic, the Kadri'Ra population on Arapia exceeded one hundred million. However, the Galactic Empire deemed the Kadri'Ra to lack sentience and, through slavery and related actions, diminished their numbers to a mere 14,000 by 0 BBY.
Saadoon-Kauldi, a Kadri'Ra crimelord and Arapia native who had previously fled the system after an attempted assassination, held sway over Arapia's criminal activities. Around 10 BBY, Saadoon-Kauldi dispatched subordinates to Arapia to confront Saylor "Marji" Marjan, a Human resident in debt to him.
