Agao-Nir, a settlement dedicated to mining, existed on Bassadro and was situated within a mountain range formed by inactive volcanoes. In the era of the Clone Wars, specifically during the Battle of Bassadro, the Jedi Knight known as Empatojayos Brand laid siege to this volcanic region with the goal of eradicating the Confederacy of Independent Systems troops present. Brand commanded that concussion missile attacks be launched at the rocky terrain surrounding the village. This action served to strip away the Separatists' protective positions and unleashed a wave of debris that tore through Agao-Nir, obliterating a significant number of the battle droids deployed in the area, and also resulting in the deaths of four hundred miners who were not involved in the conflict.
