Do not play this card unless you are certain it will benefit you. It halves the yield from the most important food fields and triggers triage almost immediately.
How to play it: Place a 1/2 token on the Hill Country, Calvus Archipelago, and Southern Colonies. These remain permanently on the game board. Then, in the next cycle, play Phase I twice in a row. Note that you repeat the entire phase, not just the alternating placement. This means that the cycle cube is also increased, a new doctrine is drawn, and a new initiative auction is held. The player with the fewest armies must also select a resource and return half of it to the supply. The rest is placed in the market.
