Akreonic Worlds

The United Lordships of Akreon have previously expanded greatly. Having spread to many of the "fresher" worlds among the stars, colonizing and developing as they went creating quite an Empire for themselves. However as they expanded they left many Tombworlds and other wrecks of those who had gone before untouched except for the most minimal of missions and stations to gather what can be gained from orbit.

While their economy is powerful, particularly those sectors working on major governmental projects, their military has suffered from a lack of tangible external threats. Now mostly being a glorified scout force, lacking sufficient power to defend their new Empire from prepared threats, given enough time this core of their military may grow into something to be feared.

Total population of the Empire is; 63.43 billion by last census. There are eleven worlds inhabited by the Xengari, eight fully colonized. Their defensive structures are currently lacking as is a navy to protect their empire. The only major starbases are around the Coreworlds, though the five other fully colonized ones do have starbases  as a general rule.

Coreworlds: Not Including the Homeworld, these worlds were initially colonized by governmental initiatives as part of the first wave of colonization.

Akreon Prime: Oceanic, Homeworld, Population 14.83 billion by last census
Cadellia: Oceanic, Population 13.37 billion by last census
Kreos Prime: Oceanic, Population 11.76 billion by last census

Corporate-worlds: These worlds were initially colonized by corporate initiatives as part of the first wave of colonization.

Qoabos: Oceanic, Population 6.13 billion by last census
Vesmeron: Oceanic, Population 8.63 billion by last census

Hearthworlds: These worlds were initially colonized by joint governmental-corporate initiatives as part of the second wave of colonization.

Botriytera: Continental, Population 2.36 billion by last census
Tuplarvis: Tropical, Population 1.07 billion by last census
Jeitova: Oceanic, Population 3.76 billion by last census

Frontier-worlds: These worlds are being colonized by joint governmental-corporate initiatives as part of the third wave of colonization.

Kustomia: Continental, Population 153 million by last census
Cugrionia: Continental, Population 762 million by last census
Promenides: Tropical, Population 605 million by last census

Tombworlds: These worlds are mostly avoided by the Xengari, however two do reside within their borders.

Usmaoter: Tomb, Presence; Small Observation station in High Orbit.
Suaruta: Tomb, Presence; Medium Observation station in orbit and a small ground base.

Could you specify how many worlds they have and their names?

This should be sufficient I believe.
