Resilon, a planet dedicated to mining, existed within the Mid Rim's Bortele sector.
The mines of Resilon were operated by both sentient organic beings and their droid counterparts. Notably, the 8D smelter droids instigated a rebellion against their masters, insisting on equitable treatment and halting their labor until these conditions were met. It was suspected, though never definitively proven, that the 8D smelter droids played a role in the demise of an owner during this uprising.
