After purchasing a row of 3 or more influence markers, you may return 3 of them to control a single monster. (Return 2 to the general supply, and place the third marker onto the related monster icon to indicate ownership). Then, immediately deploy the monster to any location containing one of your influence markers or pawns. (Sea Serpent must be on a port bordering the sea or river).

The sea serpent is limited to ship and submersible routes. The behemoth is limited to roads and flying machine routes. If either monster is defeated, return it to the Knight Guild for reuse and retrieve your influence marker.
