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!
In this level 6 adventure for 4-6 players the party comes across a man named Johann Dhomm who was transporting animals in cages to his private island where he has a menagerie (a kind of zoo) that he eventually wants to open to the public. But the animals have escaped and he asks the party to try and catch them alive for him. However, the animals are actually quite dangerous and range from Gazers to a Wyvern.
In this level 1-5 adventure for 3-5 players the party is tasked with the rpg standard mission a.k.a. catching rats in a cellar, only in this case they are not rats but guinea pigs.

People from around the world can compete here for prizes in front of a live audience. However the games will have to be tested and that's where your brave adventurers come in. This adventure contains 10 different puzzles, 10 different rewards and tips on how to adjust the encounters for players of higher and lower levels than the recommended level of 3.
