Root: The Underworld Expansion

New factions and battlefields join the world of Root! 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.
