A conflict transpired on a Viidaav species' mining world during the era of the Clone Wars.
Without the colonists knowing, Count Dooku and General Grievous gave the order to detonate the planet's mining charges. This was part of their scheme to obliterate the entire planetary surface, along with the Republic forces stationed there. Nevertheless, the Viidaav and the Republic forces uncovered this nefarious scheme. An ARC trooper managed to shut down the automated self-destruct command center, which resulted in the planet's salvation and a win for the Republic. After the fighting concluded, only a few hundred thousand Viidaav survived.
