This is the area where you enter the Abyss at X:39 Y:79. This is the gate to the Entry Bastion.
At X:37 Y:45 is a deep well that has long since dried up. If you use a rope, boots of climbing, fly or spider climb or are successful at an acrobatic act, you will find a hole in the side of the well about 80 feet down. This is how you can get to a large section of the Abyss known as Abyss: The Crimson Stronghold.
At X:40 Y:81 is a secret wall that leads to a forgotten store room. You should be able to rest here. There are a few magic scrolls here as well as a demon must be using it as a secret stash.
To the west of where you enter this abyss is a small maze of corridors. Pits are all over the place here and will spell the doom of the ordinary traveler. You can avoid these pits if your party is under the influence of Levitate, Fly or Detect Secret.
At X:19 Y:69 is a hidden treasure chamber with some minor magic items and one very cool item. Well worth the grab.
Your goal here is to destroy the creature that is at the far end of the bastion. The easy way to get to him is to enter the hall at X:31 Y:83 and walk west in a straight line until you hit a big room. Of course, you won't get the cool treasure if you do. Somewhere in that hall it will flip you around so watch for the compass to change and do a 180 when it does and keep walking west.
As you progress through the big square rooms, eventually you will find the Hemerood. He is one tough cookie. If you win the battle you will get some cool stuff. On his neck is a necklace you can't remove. While in the room, (After he is dead) click the ENCOUNTER button and cast "Tongues" to read what is says on the necklace. It give the command word for getting back to the Realmz through the portal. The word is "Vistock"
When you leave the Entry Bastion, you will enter the region known as The Pitted Lands.
