Hunt for the Thessalhydra is a short adventure published by Wizards of the Coast as a tie in to the "Stranger Things" franchise and part of the Stranger Things Dungeons & Dragons Starter Set. The adventure features characters, locations, and monsters inspired by that series. The adventure is suitable for characters of level 3-5.

In Wheloon, a city known for its vibrant green slate roofs, a new temple to Mystra is in the final stages of construction. But something rings false among the heavenly spheres- or at least among those who mouth the pieties of Mystra while plotting magical mayhem behind closed temple doors.

The goddess Erathis has never seemed the sort to demand the sacrifice of mortals in exchange for safe trade routes, but that’s exactly what her high priest has demanded. When a local ruler asks the characters to investigate the high priest, a chain of events is set in motion that could shake the city of Wyllea, and the church of Erathis, to its core. This adventure makes extensive use of roleplaying encounters and skill challenges, with fewer tactical combat encounters. There is a substantial focus on politics and intrigue. The Tariff of Relkingham is written for 3rd level PCs, but contains advice for lowering or raising the starting level from 2-4. It also contains a system for calculating an advantage or disadvantage in the final fight based on the players' actions during the adventure. Pgs. 83-103

Into the Forsaken Temple's Crypt is a short adventure for four 10th-level characters. The adventure takes place in a buried temple crypt, which has been sealed for centuries. Dungeon Masters can adjust it for higher-level characters by widening the dead magic areas and increasing the number and power of constructs and undead that inhabit the complex. The PCs have entered the Forsaken Temple's crypt and started exploring a bit. They had the opportunity to work with some drow to get past clay golems. Now they face a greater danger, but maybe they'll turn back before it's too late.

In this prelude to the full Princes of the Apocalypse campaign book, adventurers face off against the influence of Elemental Cultists in the hills and canyons of the Dessarin Valley. The four mini-adventures within are only tangentially related to each-other, and instead serve as starting points and hooks for the plots of the complete Princes of the Apocalypse Campaign. Players start in the well-described town of Red Larch; first investigating a local necromancer, then uncovering cult influences within the town, and finally heading off to infiltrate or do battle with two small elemental cultist strongholds. All parts of this adventure can serve as great places to seed hooks for other campaigns.

What begins as a simple expedition to explore an ancient jungle temple sends adventurers headlong into a search for the Dragon's Eye, an artifact created ages ago by demons in order to gain power over dragons. But where exactly is this mysterious artifact, and why do the Cloudreavers and the Emerald Claw think the adventurers already have it? Only Lady Vol knows the truth. Her deadly cat-and-mouse game leads the characters from the wilderness of Q'barra to the wild coasts of the Lhazaar Principalities and the soaring peaks of Argonnessen. There, at last, they can learn the secret of the Dragon's Eye and foil the lich queen's plans... if they survive!

Base of Operations is a short adventure intended for four 5th-level characters. DMs can easily modify the adventure to suit higher- or lower-level adventurers, or larger or smaller parties of adventurers. Simply adding a few monsters to every encounter area makes the adventure more challenging for larger parties, and adding levels to any of the humanoids can make them more of a threat to high-level groups. For low-level adventurers, make the relationship between the two factions within Brightstone Keep more strained, and take away a few monsters from each group. You can remove levels from some of the humanoids in the adventure to make it a lower-level challenge, but it is important that the orc cleric (described in encounter area 8) still have the ability to animate the dead. Still, he can have fewer minions around him when encountered, and that makes him less of a challenge for a lowlevel party.

The Approaching Swarm is a short adventure for four 9th-level characters. The party can consist of any mix of classes, but it should include at least one character that is good in wilderness settings, such as a druid, ranger, or barbarian, and at least one cleric. This scenario should prove a reasonable challenge for characters from 8th to 10th level. The adventure takes place in a swampland that is near a small settlement. The characters attempted to cross back through the swamp to their base of operations. Along the way, they may have got stuck in mud and probably were attacked by a variety of flying insects. They arrive just a bit too late to stop a massacre that occurred back at Crivdall -- the fort is ruined and it appears that almost everyone is dead or missing. Aleretheral, an insane half-orc druid who has mastery of vermin and insects, attacked Crivdall with his insects. He has often infiltrated Crivdall by posing as a harmless elf hermit who lives in the wood. In reality, he wants the settlers destroyed and out of his swamp.

The Golden Dragon, conceived as a skyfaring warship, now serves as a symbol of peace among the Five Nations. Even before the luxurious airship embarks on its maiden voyage, nefarious pirates, thieves, and saboteurs conspire to defame, steal, or destroy it. Resourceful adventurers are needed to protect the ship and its passengers, but can they uncover the secret enemy lurking in their midst? "Voyage of The Golden Dragon" is a stand-alone adventure for the Dungeons & Dragons game that immerses your characters in the Eberron campaign setting. Designed to challenge 7th-level characters, it takes heroes on a perilous journey from Sharn to Stormreach and also serves as a launching pad for adventures the world over.

Side-Trek adventure When your PCs gain access to the teleport spell, their whole world changes. That simple spell opens up instantaneous, long-distance travel. No more long overland journeys or dangerous retreats through hostile territory. All it takes is clasped hands and a word from the wizard, and poof! The PCs are where they want to go. Except that it isn’t that simple, because teleport isn’t foolproof. The off-target teleports are a matter of scattering your PCs someplace else on the map and forcing them to get their bearings and make the long overland journey anyway. But this Side Trek focuses on the really intriguing column on the teleport chart: “similar area.”

Three important citizens of Phlan, who stand against the tyrannical dragon that rules, seek to escape and find refuge across the Moonsea. Can you extricate those that are vital to the factions before it’s too late?

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.

Baron Rajiram’s forces have secured the Nelanther Isles and have scoured the Sword Coast for treasures. Now they have begun to explore a mysterious island that recently just popped into existence nearby. SEER seems to believe that an aboleth artifact is their goal. It is up to the adventurers, in competition with the baron, as well as aboleths, the Kraken Society, and the mysterious caretaker of the island, to locate the Eye of Xxiphu and avert catastrophic disaster.

Great Danger Wrought in Secrecy Legendary forgemasters now serve an evil warlord and his dark purpose.

"The Keepers of the Celestian Order, valiant defenders dedicated to destroying horrors from the Far Realm, have trapped a beholder in its lair. However, the evil aberration has proven far more dangerous than expected, and the Keepers need the help of adventurers to end the threat of Omaranthax once and for all. This Dungeons & Dragons Roleplaying Game adventure, created for Free RPG Day 2012, pits player characters against a mutated beholder and its vile underlings. Although set in the Forgotten Realms campaign setting, the adventure can be easily adapted to any* D&D world." *: The adventure mentions that it is suitable for any setting touched by the Spellplague.

Temple of the Gleaming Sands is a short adventure for four 5th-level characters that features monsters, spells, and items from the newly released Sandstorm book. You can use this scenario to introduce the new material on deserts and arid wastelands into your campaign, or you can just use it as a site-based adventure in a desert area. The scenario is set in a remote area of the desert that very few humanoid travelers visit. The temple from which the adventure takes its name has lain forgotten for centuries and is now inhabited only by monsters who use it as a base. The area around the temple should be inhospitable enough to discourage humanoid settlement.

The Land of Ash and Smoke. Once a hellish landscape of volcanic activity, now a nightmare region that hosts one of the scattered Soulmonger fragments. The fragment’s burgeoning power attracted the attention of the Red Wizards of Thay and, thankfully, adventurers who are willing to risk life and limb to keep the fragment from these vile arcanists. Can you reach the fragment before the Red Wizards make off with it? The hunt is on. Part Two of the Broken Chain Series. A Four-Hour Adventure for 17th-20th Level Characters

Despite the bitter cold that reigns here nine months of the year, the Timberway Forest has long been a source of prosperity for civilized folk who live nearby. Many trappers and hunters spend the better part of the year within its borders, stockpiling furs and meat to trade in the frontier towns to the south, where they spend their winters. Most feel that the value of these commodities makes braving the Timberway Forest worth the risk. Recently, though, a small group of trappers and hunters has awakened a terrible new menace in the forest. Based in a remote hunter's abode called the Bluerock Lodge, they hunted the animals of the woods more out of a deep-seated desire to be cruel than a need to feed themselves. In particular, they focused their hateful attention on the local Timberway lion population. Timberway lions are rather small (more like leopards), but they are known for being lithe and wary. Still, the trappers had the advantage of intelligence and tools, and before long they had slaughtered the entire pride save for its leader. As the winter worsened and game grew ever more scarce, this last surviving lion began to starve. At that point, the darker forces of nature took notice, and the Timberway Forest gained a predator like no other. Frozen Whispers is a short D&D adventure for four 3rd-level player characters (PCs). The scenario is set mostly in and near a remote hunter’s lodge in a snowy forest. The scenario can be placed in any cold area of your campaign world that features a remote tract of woodland—a copse of trees near the arctic circle, a swath of taiga near the treeline on a high mountainside, or even a normally temperate forest caught in the grip of an unnaturally snowy winter. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.
