Kozani Hive is the second hive city of Corinthe, and home to the majority of the ecclesiarchy presence on the planet. It's construction is as rich as that of Grevena Hive, but bent towards veneration of the Emperor rather than the trappings of House Mora.

Kavala Hive is the youngest of the three hives, but despite lacking the history of its sister spires, it house the system's Scholar Progenium, which is the largest in the sector, as well as the arbites headquarters. It has the largest military presence of the three hives.

The Acharnes Forge Temples are a massive, sprawling fortress masquerading as a Mechanicum forge. While not nearly as expansive as Arta Fortress, Acharnes boasts advanced fortification and deadly weaponry not seen elsewhere.

Aside from Ialysos, Acharnes is one of the only places on Corinthe capable of launching the massive transports capable of hauling the mighty warmachines of the Collegia Titanica.

It also serves as the seat of power for Corinthe's Fabricator General, Ksenia Vail, and protects numerous STC vaults containing valuable information.

Ialysos Space Port is the largest of such ports on Corinthe, is more or less centrally located between the three main hive cities, and is surrounding on all sides by the massive Arta Fortress.

It is a major shipping hub for moving goods on and off world, but is also one of the only places capable of landing transports which carry the war machines of the Collegia Titanica, making it a vital strategic point.
