Mazes of Menace – a good map

I agree it is pretty hard to read, and I think is better explained in text.

You start on Dungeon Level 1. At certain points in the game you can branch off to another area.

• You start at Dungeon Level 1, which is the top level of the Dungeons of Doom
• Somewhere between Dungeon Level 2 - 4 you can branch off to the Gnomish Mines
  • On the 3rd or 4th level of the Gnomish Mines you will find Minetown
  • The last level of the Gnomish Mines is Mines' End, which'll occur at the 8th or 9th level of the Gnomish Mines
• Somewhere between Dungeon Level 5 - 9 you will find The Oracle
• Just after The Orcle, you can can branch off to Sokoban (which you'll actually enter from the bottom and is 4 stories high.)
• There is a 40% change of a Big Room somewhere between Dungeon Level 10 - 12
• Somewhere between Dungeon Level 11 - 18 you can embark on a Quest
  • The first Level of the Quest will be the Quest Home Level.
  • The third Level of the Quest will be a locate mission.
  • The last Quest level, containing the Quest Goal is located somewhere between the 5th and 7th level of the Quest
• Somewhere Between Dungeon Level 10 and Medusa's Island you might be able to reach Fort Ludios
• Somewhere Between Dungeon Level 15-18 you will find the Rogue level
• 1-4 levels before Castle you will find Medusa's Island
• Somewhere Between Dungeon Level 25-29 you will find the Castle, which is also the last level of the Dungeons of Doom

• Right after the Castle, you will enter the Valley of the Dead which is also the first level of Gehennom (this will be Dungeon Level 26-30)
• The Lairs of three demons are located in Gehennom:
  • Asmodeus' Lair is located somewhere between the 2nd and 7th levels of Gehennom
  • Juiblex's swamp is located somewhere between the 4th and 7th levels of Gehennom
  • Baalzebub's Lair is located somewhere between the 6th and 9th levels of Gehennom
• You can enter Vlad's Tower from somewhere between the 9th and 13th levels of Gehennom. (you'll actually enter it from the bottom and it is 3 stories high.)
• Orcus-town is located somewhere between the 10th and 15th levels of Gehennom
• The Wizard's Tower is a set of three consecutive levels, which start somewhere between the 11th and 16th level of Gehennom and have the last 2 levels lower.
• There are 2 Fake Wizard's Towers levels, which are located between one to four levels above the Vibrating square
• the level above Moloch's Sanctum is Vibrating square
• Moloch's Sanctum is located somewhere between the 20th and 24th levels of Gehennom which translates back to somewhere between Dungeon Level 45-53. this is also the lowest level you can reach.

• The Negative levels are part of the End Game, which consists of:
  • The four Elemental Planes:
    • The Plane of Earth
    • The Plane of Air
    • The Plane of Fire
    • The Plane of Water
  • The Astral Plane, which is the location of your ultimate goal.

As you can see, due to it's complex design, and random generation, it is very difficult to produce a good map of the Mazes of Menace
