The sound of a thousand explosions wakes you up suddenly, as if the earth roared. You rush to the window to see what happens and you are speechless. A huge river of mud has invaded the valley where is your village. The inhabitants are swept away by the current, the animals drown in the stables. The screams echo throughout the valley. You see a soldier dragged down by the weight of his armor, a thrown rider swept by a wave of water, earth and sand. His screams are mixed with those of a mother who seeks her daughter from the roof of a house. Desperately screams her name. Then she falls. The largest dam gave way during the night, following heavy rains, and now nothing prevent the river to destroy everything. The mud was still flowing, carrying houses and shops. Some lucky ones were able to save themselves on the heights, others had fled to your palace, the only safe place. There is nothing you can do but watch your people that is swept away.
The next morning you starts to assess the damage. Only a few structures were saved, the rest is still submerged by a layer of mud. You send your few surviving knights in search of missing, and in the meantime you organize relief efforts. Some people are buried under the rubble, and must be saved. In addition, you assignments some men to bury the corpses and burn the dead animals. Your village no longer exists. It can not exist another village in this valley. The land now produce little crop, and diseases will spread in a short time. You have to move your people, but first you need to collect the necessary resources. As if that were not enough, the Rat is looking for the person responsible for the collapse of the dam, and his troops are patrolling the mountains. They must not find you, or you will be blamed for the destruction of his land.
Use your knights to quickly kill the scouts of the Rat, before they revealing your position.
The surrounding land is not suitable to build structures, you need to clean up the valley to build new ones and gather resources.
