The Burrow & Tunnels
UnderworldRoot
The Burrow is an unsuited clearing next to every clearing with a tunnel. Only the Duchy may place or move pieces into it, and the Duchy always rules it. The Duchy has 3 tunnel tokens; if it must place one with all three on the map it may first remove one. Dig: spend a card to place a tunnel in a matching clearing without one, then move up to 4 warriors from the Burrow there.
