Return to the world of Root with new factions, maps, and an alternative game deck!

The Underworld Expansion includes:

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

This expansion requires the base game in order to play.
