The Tower of Azazel is a massive tower built by and for the ancient elven wizard Azazel. The Tower is located at the center of the ruins of the elven city of Trealel Tarn. The city is a monster infested ruin by all accounts but rumors persist of fabulous treasure hidden within the city. Azazel originally built the tower to study the various planes of existence and did so for many years.
At some point portals began manifesting within the city and creatures from across the planes began filling the streets of Trealel Tarn. Demons and dragons wandered the streets and the resident elves attempted to fight back. As powerful as the elves were they were limited in their numbers and the monsters coming through the gates seemed limitless. The city became a maze of traps and artificial constructs designed to defeat the otherworldly invaders.
Finally the elves decided to create a barrier to trap the creatures within the city and prevent the world from being flooded with fould hellspawn. They knew their city was lost and spent their last drops of magical energy in erecting the barrier. Beings can enter the city but they cannot leave by normal means. Perhaps within the Tower itself lies a portal or means of escape.
This pdf introduces players to a STUPIDLY MASSIVE dungeon which is actually 77 levels of progressive difficulty that will take PCs from Level 1 through 15 and beyond. You get a huge map of the undercity, the city proper and 60 levels of the Tower of Azazel. The only escape from the tower and the city is through invisible portals that randomly transport the characters to points within the city or within the tower and on occasion it will transport the character outside the city or even to another plane enitirely.
Each dungeon level is its own seperate pdf with its own wandering monster tables and denizens.
