In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers. Known as Undermountain, this dungeon is the domain of the mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps, and mysteries—to what end is a constant source of speculation and concern. This adventure picks up where Waterdeep: Dragon Heist leaves off, taking characters of 5th level or higher all the way to 20th level should they explore the entirety of Halaster’s home. Twenty-three levels of Undermountain are detailed herein, along with the subterranean refuge of Skullport. Treasures and secrets abound, but tread with care!
"A great cat sits upon the northern grasslands, my friend, waiting to pounce on adventurers just like you." As you part the tall grass with your sword, the words of the tavernkeeper echo in your head. "He was the mightiest wizard we'd ever known, and that Lion Castle was his home." Your friends' voices mingle with the tavernkeeper's. "He's but a ghost now, haunting those halls, and waiting for an heir." The ground rises slightly. A strong wind rushes through the field. Suddenly, the grasses part, and Lion Castle rises majestically before you! "Magical riches await those who enter!" "Beware of man-beasts!" Voices flood your head again. Will you brave the haunted castle? Can you afford not to? It's all up to you in this D&D Solo Adventure. Ghost of Lion Castle is for one player only, but that one player makes all of the choices and enjoys all of the rewards. An entire castle and courtyard await your exploration. The adventure also includes a complete solo combat system. TSR 9097

The ancient ruined city of Tamoacha is familiar to a select few scholars and fortune seekers, who know of it but not always exactly where it is. Even more secluded, lying somewhere within or beneath the ruins, is a hidden shrine said to be dedicated to Zotzilaha, the vampire god of the underworld. Adventurers who catch wind of the place are likely to find its lure irresistible. Remake of the AD&D module by the same name.
