Please help me with the scenario name. All I remember is: The location is a small island on the water. The hero has 3 different castles, located one after another, horizontally: with hydras, with yellow dragons, and the third one I don't remember (possibly with red/black ones). On the path, nearby, there is a Pandora's Box and some other chests. The entire map is filled with creatures from different cities. The path is only straight, downwards, a narrow, long trail lined with creatures from different cities, 2 creatures wide. At the end of the trail, there is a portal to the enemy. In the cities, you can only buy creatures of level 7, I think.
