This map starts off interestingly. You get a single level 7 Mistress and a few small rooms to begin with. No portal, barely anything to research (including the imp spell). The idea is that you have to look for the rooms on the map to be able to build them. There are a few creatures on the map to find and help you get the bridge/library which will unlock everything you need.

However, this being an Oetelaer map, the heroes are controlled by a Keeper and this breaks the map in keeperfx. Most of them will die to starvation or infighting and should you start a fight with one, the Keeper will drop everything into battle, including many Knights and Samurais. After a while, the white Keeper got insane and started spamming CTA at two different places (probably because of locked doors). He also tortured a fairy in the one-tile slab he had for some reason.

The other two Keepers are passive and shouldn't be a threat unless you wait a long time before fortifying. That being said, a huge scavenging war is bound to happen and every single creature will start being scavenged at some point.

Also, turns out you don't need to deal with the heroes at all to win this map. Using Armaggedon, you can destroy white's heart without triggering the huge party guarding it, him being a Keeper and all.

2/5 for the beginning. A temporary fix for this map would be to remove the white Keeper.
