From Against the Storm Official Wiki
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.
From the Upgrades tab of the Smoldering City, you can spend Citadel Resources (
