Forgotten Underground Cities

Forgotten underground cities are one of the most lore-dense environments in Fatekeeper. Pre-launch material describes them as cities grown from rock and metal, lit by fire and luminescent crystals, built by

the Underdwellers during the centuries they spent isolated beneath the surface. The Underdwellers carved monumental sanctuaries and full settlements into mountain caverns; some of these cities are now contested, abandoned, or in ruin.

Atmosphere

The cities are designed to feel grand, planned, and ancient. The Underdwellers were a technocratic society, and their settlements show that influence: ordered architecture, structured layouts, evidence of education and craft. The contrast between these careful spaces and the wild surface is one of the game's recurring themes.

Loot and Lore

• Lore inscriptions tied to the Underdwellers' history of exile, retreat, and rediscovery.

• Relics - identity-shaping items often carrying explicit Underdweller heritage.

• Ingredients - rare metals, refined alchemical components.

• Engineering: examples of how the Underdwellers built mining shafts, communal halls, and fortifications.

Connection To The Surface

These cities are where the contact between the two worlds happened. When Underdweller excavations finally tore open paths to the surface, those paths went through their own cities. The forgotten underground cities are a key geographical bridge between the surface story and the underground one.
