The Northmen and their allies play hardball. The Northmen are on a rampage, and only the duergar know why. Discover the secret of the iron orb. In the lands of the Northmen, near the city of Tallborg a mysterious relic was uncovered in a mine: a perfect orb of black iron. The orb was taken to the temple. When Ulvmard, high priest of Odin lifted the orb it revealed its true nature. The orb levitated from his hands, floating before him. The orb had changed Ulvmard, bestowing him great powers. The orb spoke to him with flattery and advice. As he became reliant on the orb, its power over him extended, bending him to its will and taking control. It used him to further its agenda: destruction of the dwarven race and restoration of the duergar! Claiming to be acting on Odin's behalf, Ulvmard lead the Northmen to rise up against the dwarves, and ordered raids to pillage the southern kingdoms for the materials he would need to construct a colossal iron warrior to defeat the dwarves. This adventure has viking and norse mythology influences. Pgs. 50-71

The Dread tunnels of Ruxbar were created by a cult of a lesser evil deity of the giant pantheon, known as Jargain to serve as a planar gate in hope of bringing chaos and destruction to the natural order of the world and power to the one who would control the gate. Ruxabar was the high cultist who completed the ritual but to his surprise nothing of what he expected came through the gate. Plague creatures, toxic gases and vapors, diseases of all kinds and decay lay quick waste to him and his cult. For some time the gate remained open and the settlements nearby were afflicted with diseases never seen before. The nearby town of Stagwood was quickly abandoned due to the plague. Rumor has it that the gods have weakened the gate and the cult has been destroyed. The remaining villages that managed to somewhat resist the plague are now hiring brave adventurers to venture into the tunnels and close the planar gate for good! Are you capable enough of surviving the horrors that reside in the Dreaded Tunnels of Ruxabar? Published by Mistfactor Press

The ground-breaking introductory adventure for Dungeons & Dragons that served as a DM aid in the first D&D Basic Set, released by TSR in 1977. This set included a 48-page rulebook covering the first three levels of play, and was skillfully edited by Dr. J. Eric Holmes from the original 1974 D&D rules written by Gary Gygax and Dave Arneson. The original set included an exemplary dungeon level, but it was a loose collection of examples and not geared toward starting characters. Holmes advanced this concept by writing a new thematic dungeon with a strong backstory, creating an adventure that has remained a fan favorite over the decades. Officially, its only title is "Sample Dungeon" but colloquially it goes by various names based on Zenopus, the doomed wizard who built the dungeon under his tower

Numerous towns sit in the shadow of Rak’Sarn, a mountain of flames and death. Each day near sunset, the volcano lets loose a blast of molten rock and ash, and the ancient red dragon Dal’Sarnquin swoops down the mountainside.

When the Purple Planet began its slow decline, factions arose to vie for the final resources of the dying world. In the days of the Last Wars, the Ascendant Masters used their knowledge of cybernetics and genetic engineering to create increasingly powerful and grotesque biological weapons. One such weapon was Sotark the Destroyer of the long lost House Memniscene. Damaged and placed in a cryogenic regeneration capsule, Sotark has slept away the ages while the House above him eroded away under the weirdling sun. Over time, the capsule has failed, but still Sotark sleeps on, diminished, but not destroyed.

Listen up! You're in my dungeon now, Morty! On Earth C-141, I'm a LEGENDARY D&D adventure writer! When people think of impossibly difficult dungeons or winding, labyrinthine maps, those things ain't Gygaxian - they're SANCHEZIAN! I do whatever I want over there, and they eat it up! I'm a celebrity Dungeon Master there, too! My livestreamed show, Cynical Troll, gets a billion views a day! It seemed a little selfish to contain all that GREATNESS to a single dimension, so I lifted one of the all-time favorite Sanchezian adventures and snuck it back here to dimension C-132. (Usually that kind of s**t is frowned upon, but it's just a D&D adventure. We're not exactly violating the Prime Directive or whatever.) This is a good old-fashioned dungeon crawl for a party of 1st-level adventurers, whose character sheets in this box should also contain. They'll probably reach 3rd level by the end of it. So here it is. This adventure brought peace to a warring galaxy. What did you ever do? Oh, you picked up this adventure? Good start. And awaaaay we go!

A shrewd, spell-using green dragon has taken over the deepest chamber of a limestone cave as his lair. The dragon has persuaded a tribe of troglodytes to live in the outer chambers as a sort of "protective buffer" in return for gifts of magical treasure. The troglodytes cherish the useless bits of magic without realizing their modest worth. The outer chambers of the cave are protected by the troglodytes, the beetles and centipedes the troglodytes raise as cattle, and wild creatures. The green dragon uses traps, illusions and magical devices to protect his inner chamber. Wyrmhaven is the second dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

The Last Point is a prison and outpost of the Corrive Empire, a realm ruled by a cruel green dragon named Lady Corrive. The Corrivians are well known for their hatred of magic users, and their extensive slave trade industry. A forest realm with coasts on three sides and mountains running through the center, Corrive is rich with a variety of resources. However, the rocky northern coast is out of the way of their navy and relies heavily on hired ships to help transport various goods including prisoners and slaves to isolated outposts, training centers, and slave colonies. The northwest coast of Corrive is rocky and many parts of it are elevated, making it isolated from much of the mainland. The Last Point is a recycling center where captives meant for death row who are either deemed “not important enough” to execute publicly or “too disgraceful” to execute publicly are sent to be tortured and then killed. The place seems to operate on sort of a “well, we have too many so some have to go now” policy. The Last Point has no official deadlines for killing.

Decades ago a group of adventurers saved the town of Logan’s Bluff from a humanoid incursion.

In the decades since the battle peace has reigned but has recently waned with the advent of more humanoid sightings. Some have wondered if Forstal’s tomb is drawing the humanoids back for revenge.
