Water, towers, walls, canals, and clear land blocks the spread of fire. Lava Volcanos produce lava that flows downhill and fills up valley floors. Lava destroys everything in its path, and sets anything nearby on fire. Blob Soldier Blob soldiers are the basic military unit.

Middle altitudes Farms can survive in these higher areas, but do not produce as much food unless near a good source of water. It is hard to grow food in the highest areas due to the lack of water, but a good canal system can help. Consider placing a military base on top of a mountain. Soldiers can travel faster downhill than uphill, so it is easier for them to reach an invading army if they are on top of a hill.
