Gold Beard Fortress

I am reposting the dungeon that I have drawn with How to Host a Dungeon (and my friend H.)
(there is some additional notes on the map).

Some notes about the history of the dungeon.

Primordial Age:

• Three primordial beasts inhabit the region: a cyclop, a gigantic spider and a sentient giant slime. 
• The purple plague infect some of the caves. 

The Age of Civilization:

• The dwarf's runes point toward a deep gold vein. 
• Gold Beard Fortress is build.
• The red gold vein is found and named "The Setting Sun". 
• Construction of the Great Hall of Deep Shine.
• Construction of the red workshops.
• Construction of the Hall of Records.
• Foundation of the underground city of Glorious Gleam. 
• Construction of the royal secret chamber and forging of the first Red Sun. 
• The dwarfs dig too deep and awaken the Beast from Below. 

The Great Disaster:

• The Beast from Below summon a underground river to flood the dwarf's tunnels to hunt them. 

The Age of Monsters:

• The water level diminish and monsters settle in the dungeon.
• The Gnolls - Antling war. 
• The Gnolls vanish, hunted down by dwarven ghosts. 
• The Purple plague orcs tribe settle in the now empty dwarven city and prosper. 

The Age of Villainy:

• The Lich King settle in the dungeon and enslave the purple plague orcs.
