Brontes
The Brontes system was a core Confederate system. It has one colony on the world of Brontes IV, with a small orbital platform for space traffic in orbit of the planet. Unlike most planets in Terran space, Brontes IV has a more diverse environment, ranging from the typical wastelands of Terran colonies through highly volcanic areas to large jungles. Several areas of the planet have large valleys rich in mineral deposits.
The colony was attacked in the initial Zerg invasion of the Koprulu Sector, but the combined efforts of the colonial militia and a detachment of Tassadar's expeditionary force prevented the invasion from achieving immediate success. The actions of the Protoss and a rebel Terran group known as the Fist of Redemption led to the Swarm losing control of Incubus Brood to Atticus Carpenter, the leader of the Terran rebels.
Following a long war of attrition against the Protoss and the colonists, the Zerg were able to overrun and destroy their adversaries, ending the campaign with the culling of the renegade Incubus Brood. The status of the planet since the end of the Brood War is not known.
