Here's the current draft for Thalamhan's map, including the names of all four cities and Danuas's location! Things are most likely going to change in the future but for now, this is the layout. It's not entirely accurate, for one the scale is probably bound to change and the map presents the colony as very vertical when it's not. I'd probably need to make it in a 3D software for it to be the most accurate it can be, but that can be for another time

When Danuas tunneled into the planet millions of years ago, the series of interconnecting cave systems she left behind would become Thalamhan. Early Thalamites would found Danann, the capital city, and during the Branching Era centuries later, they would expand upward toward the surface, founding the other three cities as well as many smaller towns and villages. Thalamites also live along the tunnels connecting each settlement to another.

Danann is the capital and cultural center of the colony, home to the Sacred Grounds. Beneath it is Danuas, accessed only by the cityspeaker through an entrance known as the Well of the Titan.

Loc Faore is the agricultural capital, a city built around a large lake of the same name. The settlements that surround it are along the streams that come from the lake, home to most of Thalamhan’s farmers.

Astorea is known for its high population of smiths and metallurgists. Its nickname is Little Danann, as it has the second largest cultural scene in the colony, particularly textiles and art.

Tollana is unique for being a mostly vertical city, so most of its population are Thalamites with flight based alternate modes. Many scientists and engineers including some from Danann have residences here, as it is the closest city to the surface, perfect for researching the planet and sky themselves.

The dark regions that surround the colony are the Darklands.
