The Underworld Expansion includes:

• The Great Underground Duchy: an imperial faction that blends the flexibility of the Marquise with the escalating Eyrie Dynasties.
• The Corvid Conspiracy: a secretive faction that plans plots directly into the hands of their opponents.
• Two new maps: create tunnels on the mountain map or fight to control the ferry on the lake map.

This expansion needs the base game in order to play.
