AL - Sunless Citadel.

This is an Adventuers Leage game focusing on the Sunless Citadel from Tales From the Yawning Portal. Starting at the famous tavern, this adventure concerns a once-proud fortress that fell into the earth in an age long past. Now known as the Sunless Citadel, its echoing, broken halls house malign creatures. Evil has taken root at the citadel’s core, which is deep within a subterranean garden of blighted foliage. Here a terrible tree and its dark shepherd plot in darkness.

Amid the bustle of Waterdeep, within the Castle Ward where barristers, nobles, and emissaries battle with word and contract, stands an inn not quite like any other. Before there was a Castle Ward or even what could be recognized as an ancestor of the City of Splendors, there was a dungeon, and in that dungeon begins the tale of the Yawning Portal.

In ages past, the mighty wizard Halaster built his tower at the foot of Mount Waterdeep and delved deep into tunnels first built by dwarves and drow in search of ever greater magical power. Halaster and his apprentices expanded the tunnels they found, worming out new lairs under the surface for reasons of their own. In time, their excavations grew into the vast labyrinth known today as Undermountain, the largest dungeon in all of the Forgotten Realms. Halaster eventually disappeared, as have all his apprentices, but the massive complex he built remains to this day.

For untold years, the secrets of Undermountain remained hidden from the surface world. Everyone who entered its halls failed to return. Its reputation as a death trap grew to the point that criminals in Waterdeep who were sentenced to die were forcibly escorted into the dungeon and left to fend for themselves.

All of that changed with the arrival of two men, a warrior named Durnan and a ne’er-do-well named Mirt. The duo were the first adventurers to return from Undermountain, laden with riches and magic treasures. While Mirt used his wealth to buy a mansion, Durnan had different plans. Durnan retired from adventuring and purchased the land on which sat the deep, broad well that was the only known entrance to the dungeon. Around this well he built a tavern and inn that caters to adventurers and those who seek their services, and he called it the Yawning Portal.

Through the gossip that abounds through the tavern, you have heard about a place with great danger in return for great riches. Are you adventurer enough to take on the challenge?
