|Appears in||The Deeper Dungeons|
The player starts in a big area mostly walled off with Impenetrable Rock, with only a handful of choke points leading to the main enemy of the level, a hero castle surrounded by a moat and Guard Posts. On the bottom of the map is a blue Keeper next to the hero castle above and a giant lake with Tentacles, Fairies, and Samurai to the right, leaving him with not much space to work with.
The Bridge room is in impossible to obtain in this level, and since the hero castle is completely surrounded by either lava or water, in order for the enemy Keeper to attack you or for you to attack him, you must first deal with the jam-packed hero castle in the middle.
In order to even access it, you must dig tunnels that cave in to multiple different ambushes and Boulder Trap, eventually leading to a neutral Graveyard and a Gem Seam. To the right-most side of the map is a series of cave-ins with Samurai and even Knights that guard a Dungeon Special and access to the white castle.
The entrance to the castle has a very impressive ambience for Dungeon Keeper, with fog, leaping lava droplets, completely closed off from the level by Fortified Walls, a lava moat, outposts with Archers and Priestesses, and a small patch of land leading to the Iron Door, which Imps seem to adore fighting for, for some reason, even if the enemies will obliterate them before they even get to it.
From the hero castle you can access the enemy Keeper by digging through a cave with a Boulder Trap and 2 level 10 Giants and a Steal Hero special, going down and to the right there's a lake with Fairies, Samurai, and Tentacles all waiting to be slaughtered and used as Vampire food.
The blue Keeper itself is very anticlimactic, which you can breach without even using the Destroy Walls spell, and you can prepare your grand entrance with many Boulder Traps and unleash them on the enemy Keeper's claustrophobic dungeon before unleashing the Vampires to kill anything else that is still moving.
