The Thrice-Damned House of Thrune wants to seal the Inferno Gate, an uncontrolled portal to Hell, and the villainous adventurers are called to accomplish the task. To acquire the components and perform the ritual, they must first face down a hellspawn thieves' guild, the Hellknight Order of the Pike, and the knights of the Glorious Reclamation and their celestial allies. But before they can complete the ritual, the characters may be forced to examine their options—is closing the gate the best plan for the future? Will the villains obey their orders to close the gate to Hell—or might they make a deal with a devil for control of the portal? Or will they only become the latest in a long line of sacrifices to the Inferno Gate?

Death slithers across the Dunes. Nightmares of desert horrors trouble the dreams of the innocent while raiders grow ever bolder beyond the walls of the great city-state of Tyr. Bandits and merchants chase rumors of a temple hidden in the desert, an ancient shrine to the primordial Ul-Artha said to safeguard a fragment of the artifact known as the Crown of Dust. Can the heroes recover a caravan lost in the wastes, repel the threat of vicious raiders, and win the relic form the perilous temple? Now that Tyr is free of Kalak the Sorcerer-King, opportunity abounds in the city and the surrounding wastes. But some see Kalak's fall as the beginning of Tyr's end, and the unpatrolled deserts nearby are rife with danger. Outlaws openly defy the city's Revolutionary Council and threaten outlying holdings. If Tyr is to thrive, heroes must arise to tame the lawlessness and evil that threatens the free city.

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 the kingdom of Keystone, at the mouth of the Manyforks River, stands the port city of Barnacus. It was founded two hundred years ago, and its strategic military and commercial location has made it the second most important city in the kingdom. The city is under the rulership of Haermond II, Duke of the province of Elcadan, a half-elf of high esteem who has been in charge for more than a century. His outstanding commercial politics have made the city very prosperous; almost every trade company in this part of the continent has a counting house in the port of Barnacus. Because of this prosperity, the city has suffered many pirate raids, and thieving activity is a fact of life for residents and visitors alike.

An ancient and mysterious race revisits Freeport for the first time in two centuries. The adventure culminates in an encounter with a strange new race. The adventure from that point is up to the GM, but could include the PCs facilitating diplomatic relations, negotiating recovery of ancient artifacts without bloodshed, or working with an underground rebellion to rid Freeport of the Strangers. It's probably not an adventure to take on as a beginning GM. NOTE: The Tales of Freeport that contains this adventure is NOT one of the versions currently available in the Green Ronin store. Those contain short stories. This is an older item that appears to no longer be available from Green Ronin. It is possible that the adventures within it have been included in other products since then. But I have linked to the original product on DriveThru RPG.

Something is very wrong in Stormport: Corruption runs rampant among city officials, more and more people turn up missing every day, dark prophesies of Change convert new believers, and rumors persist of a demonic beast with a taste for human flesh that stalks the alleyways. Worse yet, spring is overdue; winter refuses to relinquish its icy grip. Only one vile force could cause such chaos: The illithids have risen up once again, ready to enslave the surface races. Now, as never before, the world needs great heroes, mighty adventurers who will challenge the illithids; dark agenda. A Darkness Gathering is the first of an adventure trilogy (continuing with Masters of Eternal Night and concluding in Dawn of the Overmind) that pits brave adventurers against the brain eating mind flayers. Dungeon Masters can run each individual adventure of the trilogy separately, or they can be linked together to form a seamless, epic-length adventure.

The party makes their way into a small mining village by the name of Skalintown. They quickly realize that the people here are terrified, hiding behind closed doors and peering out through boarded up windows. A gang of criminals that call themselves The Calamity have promised to destroy the city and everyone in it if they don't receive a tribute of twenty thousand gold by the end of the week. This is a poor town and even with everyone's wealth combined, it doesn't come close to that value . . . but they are fighters. Perhaps all they need to hold back these invaders is some help. The deadline is four days away and the closest town that would be able to help is three days travel one-way. Skalintown tried to reach out for aid, but no one cared enough to risk their own lives to help them. Now they must rely on your players for help. The party will need to rally the townsfolk and strategically decide how to prepare for the assault. Do they dig trenches to trip up enemy wolves, do they train the townsfolk to use crossbows, or perhaps they create explosives to detonate when the bandits make it into the city? Each of the party's decisions affect the final battle and means that every group will have a unique experience in their fight against The Calamity. This adventure is heavily influenced by the traditional Wild West shootout. Try to capture that feeling for your players by playing music of that era, in the way the townsfolk act and speak, and the way the town itself is operated. There are thousands of different options for the fight and if your players play their cards right, they make quick work of the gang and earn a pretty penny while they do so.

Blood and Gold is an adventure involving crime, drugs and vampires. The quest takes place in an urban area and can be played in any (low) fantasy campaign setting. This scenario features a new captivating and deadly drug. The storyline is hardboiled and probably better fitting for characters of low morality, who won’t take to heart when it comes down to beating people in order to extract information and working for thugs and criminals. Still, the party can be kindhearted and their reasons for meddling with a shady crowd can be for a just cause. But by the end of the day, they themselves will be tempted with the pleasures of sinister life. Adventure Synopsis: Vampire Aris is a self-proclaimed prince of thieves and murderers. He is a ruler of the underground and a demon of night. Aris rose to power through gold and a drug he created from his own blood.

The ancient Vampire is furious as his dominion is shaken. He is set on revenge and blood will be shed, mortal and immortal alike. Published by: Adventurer's Inn

A political wedding is threatening a major source of income for the Thieves Guild Ebonclad. Ebonclad would like to see the affair disrupted and the couple never wed. Such a job may be risky, and its outcome could very well start a war if done poorly or without subtlety. That’s why a team of promising agents has been assigned to handle it. The mission’s goal is to disrupt the upcoming wedding of Camilla Swain and Le’Nal Beshiin, to ensure Ebonclad keeps a revenue stream open that their marriage would surely close.
