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

Centuries ago, a beholder named Yeryl fled from the place of his birth and wandered the countryside in search for a place to call home. After many sleepless nights spent carving out a safe nook for himself in the wilderness, he at last slipped into slumber. In his dreams, he found an ideal place for his lair: long-abandoned ruins hidden amidst a dull and barren valley. Yeryl spent years transforming the place to suit his paranoid designs. Visitors were rare enough, and the few that made it to Yeryl’s lair were quickly destroyed or forced into the beholder’s service, building the lair ever deeper and more magnificent. As time went on, Yeryl finally completed his task. Safe at last, but with nothing to occupy his mind, Yeryl was struck by melancholy; was this lonely and empty life truly what he had chosen for himself? On that day, Yeryl made a decision: next time an adventurer came to his lair, he would welcome them in. With this resolution in mind, Yeryl began to dismantle his traps and replace them with ones he considered to be more fun. Unfortunately, for all his good intents, Yeryl has not yet realised that killing people is a bad way of getting them to like him. Yeryl's Super Happy Fun Murder Dungeon is a highly obnoxious and mildly ridiculous collection of traps, combat and puzzles designed to test your players' wits and patience. It is optimised for a group of four to five 3rd level players, but the text also contains a guide for level adjustments for different sized groups.

Most adventurers like to think that when their number is finally up, their colleagues will bring them home, either to be raised or at least returned to their families for a proper burial. But how far will the PCs go in order to do right by a fallen adventurer? And will they draw the line at hauling his coffin out of the Underdark? Pgs. 20-40

*THIS IS A D&D NEXT/5E PLAYTEST ADVENTURE* Imani, a Turmishan wizard and former adventurer, seeks the aid of heroes to infiltrate Dretchroyaster’s lair and recover the Diamond Staff of Chomylla—the key to powerful magic and wisdom locked away for thousands of years. In addition to his own sagely interest in the lore of lost Uvaeren, Imani recognizes the dangers of such powerful magic falling into evil hands. The dracolich has secured the staff in his lair’s cen- tral chamber, using ancient wards of protection that can be bypassed only by four artifact-idols once belong- ing to a cult of Bhaal. Each group of adventurers enters the dungeon through a different section of the dun- geon—a forgotten temple of Bhaal, a vast underground lake, a troglodyte village, or Dretchroyaster’s vaults. Dretchroyaster’s lair is no simple set of caverns and ancient ruins. It sits atop a source of great power and energy, which the dracolich and his Cult of the Dragon allies hope to use to unlock the secrets of the staff. Only by undertaking a unified assault against Dretchroyas- ter’s lair can the adventurers hope to recover the Diamond Staff and survive the dracolich’s fury. The adventurers must make their way through the lair and recover the Bhaalite idols that will help unlock the Diamond Staff, all the while dealing with the lair’s creatures and avoiding the dracolich as he pur- sues intruders. Entering the Chamber of the Diamond Staff, the heroes must overcome its magical wards and claim the staff before being slain by the dracolich and his servants.

It's all over (and literally so) after midnight. A mission with an unforgiving deadline. The characters must remove the magically-infused remains of a dead wizard and his medallion from a crypt. Pgs. 10-23

The sewers beneath Mulmaster have always been dangerous, with countless stories of brigands, murderers, and worse that lurk beneath the streets of the City of Danger. But those stories pale in comparison to a new threat under Mulmaster, one brought to light by a strange and disturbing corpse recently found. It is up to you to learn the terrifying truth of what lurks below.

For the past several days, dozens of strong earthquakes have rocked the coastal area surrounding the underground Temple of Poseidon. Since the first quake, there have been a growing number of reports of strange events and macabre occurrences throughout the area. Several families near the temple have abandoned their farms and refused to return. They claim to have been terrorized by inhuman specters who prowled about their farms late at night. One of the farmers says he found a farm animal crucified and eviscerated in a ritualistic fashion on his front porch. Following the first tremors, all communications with the Temple of Poseidon, seemingly the center of the troubled area, were cut off. Messengers dispatched to the temple to request guidance from the Holy Oracle located there have not returned. Now the darkness has spread to this town. Unnatural births have occurred. Strange cries can be heard in the night, and there is a cowl around the moon. Magical divining has proven useless in naming the dark forces that invade. Many of the townspeople have already abandoned their homes and those who remain have but one recourse left: They have sent out a cry for hardened adventurers, experienced in dispatching evil. They must travel to the temple to discover the fate of the men there, and, if possible, elicit their help in destroying the growing heinous power. Pgs. 31-46
