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!

"For Blibdoolpoolp!!" "The power of the mind and belief are wonderous, often leading us to manifest things that aren’t real. For the kuo-toa, this power is heightened, allowing their collective belief to manifest gods." Two tendays ago, a paladin of Torm was kidnapped by kuo-toa. In a strange turn of events, she was mistaken for a kuo-toa god, and whisked off to their underground lair. Barria has managed to pose as the god and now shakily leads a small faction of kuo-toa while trapped underground. With her influence being increasingly scrutinized, and with the different kuo-toa sects on the brink of civil war, it’s a dangerous time, even for a ‘god’… The heroes’ mission — rescue the paladin from the kuo-toa oceanic lair before she’s transformed into a kuo-toa god. The kuo-toa are an Underdark-dwelling race of fishlike humanoids. Different sects worship different god-like beings, each god manifested through the strength of a sect’s collective zeal. Such “gods” feature prominently in this adventure.

The lost city of Archaia - an ancient ruin sunken into the earth - lies deep in the badlands. In recent years, caravans from Eastdale have come under attack from orcs, goblins, and worse.

In Temple of the Dragon Cult, the characters are called in to pursue a dragon that the king’s army was able to wound but not kill. It seems straightforward enough: the army tracked the dragon to its lair, and all the characters have to do is go in and kill it.

The party approaches the Dwarven Kingdom of Narol'Duun, where things are far different than in your typical dwarven empire. The first major difference is that Narol'Duun is split into three distinct categories of dwarven tribes based on the main type of ore that they mine and refine. The dwarves take on characteristics of these ores - the Cobalt Dwarves having a tinge of blue to their hair, the Copper Dwarves having tough skin and beards of shining reddish-brown, and the skin of the Iron Dwarves is a deep grey in color. These dwarves engage in trade and drink, but the one thing that they are sure to never do is breed outside of their respective tribes. To be found in a relationship with a dwarf of another tribe is to be exiled to the surface - a punishment worse than death for most of these dwarves. On this particular adventure, the party finds themselves caught up in a case of forbidden love between a royal member of the Cobalt Dwarf family - Nadom Glintstone - and a simple merchant woman from the Copper Dwarf tribe by the name of Lajeera Copperfist. They have been doing their best to keep their love a secret for they both know the risks, but the Cobalt King, Norgith Glintstone, has suspicions and is deeply afraid of the damage such a scandal could have on his family's reputation. He doesn't want to draw any attention to the situation, so it is difficult to find a dwarf of his own tribe that could look into it further, so when the party comes along he sees it as a perfect opportunity. He will hire the party to look into the situation with Nadom, offering grand rewards in exchange for the truth if they can provide proof. The party will be torn between multiple threads of possibility in this adventure – telling Norgith the truth about his son's affair with Lajeera, helping Lajeera to permanently change her form to that of a Cobalt Dwarf so they can be together, or perhaps even trying to end the tribalistic ways of the dwarven kingdoms all together. This is a heavily role-playing based adventure, perfect for those who would rather talk their way through a difficult situation than cut their way through it, but there is still some combat along the way depending on the party’s choices. This story will decide if love can win out against all odds or if the temptation of coin is greater than the happiness of others.
