If you have not activated the hidden quests, see chapter 1.2. You will find Lester the Farmer near the cows in the town. If your character is level 15 or above, Lester will give you the Rune Bomb. Take it to the bridge adjacent to where you start. Standing on the bridge, drop it on the alien like thing on the ground. It will blow up the entrance to the Hive (The Nest). Go back to the Farmer and he will give you the Auric Amulet.

If you have activated the hidden quests (see chapter 1.2), you will not find Lester the Farmer. Instead, you will find the Complete Nut, also standing by the cows. In the Hive you will find one gray suit lying on the ground somewhere on level 3, and one brown suit lying on the ground somewhere on level 4. Bring the brown suit to the Complete Nut and he will give you the Bovine Plate.

If you have activated the hidden quests (see chapter 1.2), you will find a little girl standing close to the bridge just above the one that leads to the Hive. She will only appear once you have been to the Hive. When you kill the Hork Demon on level 3 of the Nest, he will drop Theodore, the teddy bear. Take it to the little girl and she will give you a random magic amulet created from an ilvl of 26. If you have not activated the hidden quests, the Hork Demon will drop a random magic amulet also created from an ilvl of 26.

The Defiler is the Boss of the Hive. Killing him will give you the Cathedral Map.

Go to the graveyard by the church. Drop the Cathedral Map on the huge new grave you find there. It will open up the entrance to the Crypt.

You will find the Cornerstone of the World (the CoW) in a small room on level 1 of the Crypt. By placing an item on it, that item will be available for another character of yours in other games. There is only one Cornerstone of the World and it is common for all games; thus, as soon as you pick up the item on it in any game, you will no longer be able to get it from any of your games. Remember that you should never be in the Crypt with any of the two characters that are involved in the swap for it to work. The reason for this is that the game will save and restore the content of the CoW if you are on level 1 in any save game. The effect may range from not being able to transfer the item at all to actually duplicating the item (which, like the infamous cursor duplication is of course a bug). The table below should clarify the result. I recommend that you always save the game while in town when you want to transfer an item via the Cornerstone of the World. This quest will never show up in the quest log.

On each of the first 3 levels of the Crypt you will find one Torn Note. When you have found all three, they will combine to the Reconstructed Note, which tells you about how to open the room to Na-Krul. This quest will never show up in the quest log.

Na-Krul can be found in a small room on level 4 of the Crypt. If you open his room by pulling the lever he will be a very tough opponent. However, if you read the books outside his room in the correct order, he will come out severely weaker (see chapter 5.2.4 for the difference). The correct order is:

1. In Spiritu Sanctum
2. Praedictum Otium
3. Efficio Obitus Ut Inimicus

When killed, Na-Krul will always drop four items according to the table below.
