Use different parts of the village for map in different scenarios. In first scenario, the battle should take place in west, behind the river. In second scenario, the player should try to hold the enemy before the river (Lemyr is surprised that the enemy has crossed it when he returns). During the third one, the orcs have broken the defenses and besieged the keep so the player has to push them back behind the river and defeat them there for once and all. (The part for scenario 16a/18b is to be decided.)
