Overview

Smoldering City with no Upgrades

The Scorched Queen has decided that the Smoldering City requires 7 new great work projects: the Obsidian Archives, the Monastery of the Vigilant Flame, the Pioneers' Gate, the First Dawn Headquarters, the Dim Square, the Brass Forge, and the Vanguard Spire. As you unlock Upgrades, Buildings will start to show up in your Smoldering City backdrop.

Smoldering City Upgrades Options

From the Upgrades tab of the Smoldering City, you can spend Citadel Resources ( Food Stockpiles, Machinery and Artifacts) to construct and upgrade these great works. Each great work improves your Settlements' chances for survival in a particular way, and certain upgrade levels will unlock new game features.
