Enemies: Heroes.

     The heroes know your location. And they're coming to get you. From all sides. This realm is the toughest so far: you will need to use the overhead map a lot, to see where the enemies are coming from. It gets really hard, dragging your creatures from fight to fight without really enough time in which to rest and heal up.

     The first thing you want to do is start claiming all the corridors, north, west, south and east. The further up the corridors you get before the heroes appear, the further away from your realm the heroes will be. Use your transferred creature (there is no excuse for not having one) to win fights quickly - against 2nd, 3rd and 4th-level opposition, it should be able to do so. If you've transferred a Dragon, use the possession mode and apply flame breath (you can tell whether your fire is accurate, the enemy will turn red; if he doesn't, then momentarily stop breathing fire, turn round a little bit, either back off or get closer, and then start blasting again, keep trying until he turns red - this means he is quickly getting hurt.)

     Get your creatures training and researching as fast as you can, never mind manufacturing - you want to research at least as far as Speed Creature, Heal (the two useful spells) and the Torture Chamber (to attract mistresses). Once you have all these, there is no further need to research, so get all your warlocks and dragons in training (if necessary, sell one of your Hatcheries off to build a second Training Room. You don't need too many imps in this realm, only enough to keep the gold coming in to train your creatures.

     (Note: Just to the south, off the western corridor, is a room with a boulder trap and two Increase Levels in it. Set off the trap at the cost of an imp, let it rumble around the room until it runs out, and collect the two Increase Levels. Use them as soon as you have a lot of useful creatures - i.e. as many as possible of all the available ones, apart from Trolls and Demonspawns on the grounds that there's no point in attracting demonspawns when you can get dragons.)

     Also look very carefully at the northwestern passage out of your library. It leads out to the lake that surrounds this island. There are four Specials in this lake, but it's not much use as you probably don't have time to get them - except, possibly, the nearest one, in the northwestern corner, which is another Increase Level - which might actually be of use to you. The two Resurrect Creature specials in the northeast and southeast corners will probably be of no use to you. The Transfer Creature special in the southwestern corner is another matter, but no use to you in this realm.

     A small Prison can be useful at times, if you can knock enemies out instead of killing them. Don't bother torturing, just let them starve, then drop the Skeletons straight back into the fight and let them kill or be killed. Keep them apart from your bile demons, as usual.

     Eventually, the enemies should stop coming from all directions. If you've actually managed to avoid using the Increase Levels so far, then now is the time to use them. If you've managed to get either of the Resurrect Creature bonuses, then now is the time to use them as well - preferably, before using any Increase Levels you may have saved. Train creatures, mine gold as much as you can during this brief respite, and expect more enemies to come at you, this time of higher level - you won't be able to do it with your transferred creature alone any more. Eventually the Lord of the Land will come in with his most powerful minions, from the east... If you're lucky, you should have managed to save up enough gold to use the Lightning spell productively. If you've researched the Chicken spell (which you may or may not have been able to do), then test it out on the Knight himself...

     If you wish, after you have won, you can use the same trick as you did last level (training only one creature, keeping the gold supply up if necessary by building and selling magic doors in the workshop - build a larger workshop to do this, you need at least 36 squares: not that you really need to, the enemies have dropped so much gold, and there's a lot available) to keep your gold supply going long enough to train your chosen transferred creature as far as you can. Or not: it isn't really that necessary to have a transferred creature at all in the next level, although it can make things much easier...
