Defense Posts in Claiming Cosmos slow enemy attacks on nearby borders. Cost, placement, and folklore.
A post is a promise: someone is watching this road or this cliff. Paint them like lighthouses so friends can find the line, and enemies can dread it.
Buffs nearby borders (checkered ground). Enemy attacks are slower and take more casualties. Cheap scaling cost, cap $250,000. About 5 seconds to build.
