Core Worlds

The Core Worlds were originally thirteen planets ruled over by the Terran Confederacy. Their architecture was rather uniform.

Unlike the Fringe Worlds, the Core Worlds were not characterized by location, but simply by their importance. Under the Confederacy, the Core Worlds often relied on exports to remain viable. By the time of the Confederacy's fall however, nine of these worlds had been laid to waste by the zerg.

Under the rule of the Terran Dominion, the term "core worlds" is still in use, but it is unknown if the terminology remains the same. With the zerg invading Koprulu once again in 2504, the Dominion focused on defending just these worlds and opened up conscription centers on them.

Known Worlds

Known Confederate Core Worlds included:

• Brontes (semingly invaded)
• Char (invaded)
• Chau Sara (invaded, now a Kel-Morian Combine world)
• Dylar IV (invaded, now a Terran Dominion world)
• Korhal IV (recovered, now the throne world of the Terran Dominion)
• Mar Sara (invaded, now a Terran Dominion world)
• Tarsonis (invaded)
• Tyrador IX (survived)

With the rise of the Dominion, Korhal became its capital, Mar Sara (formerly the eighth Confederate core colony world) was resettled by the Kel-Morian Combine and Tyrador IX came under Dominion rule.

The Dominion Core Worlds were assaulted by the zerg in 2504.

Notes

According to the manual of the original game and Overmind, the Confederacy consisted of "nearly a dozen" and "thirteen worlds" as a whole respectively. With the revealing of numerous other Confederate colonies, it appears that this number has been retconned and that the thirteen worlds mentioned were what are now known as the Core Worlds.
