"The Dark Forest" is an elder shadow drake lair suitable for four 8th-level characters. This adventure can be completed in one session. A hidden grove within a dark forest has been home to a tribe of alseids for generations. The tribe's most recent leader and spiritual heart was an alseid shaman called Riatha the Raven. Within the grove lies an ancient ring of standing stones atop a burial mount. Here, Riatha conducted sacred nature rites to honor and bless the forest and the tribe. During one of these ceremonies, the ground rumbled and a column of dense black energy shot straight up from the burial mound and into the night sky. Thick darkness enveloped the area, and the suddenly blinded alseids heard terrible roars. An instant later, the darkness dissipated to reveal a mysterious pool ringed with skulls among the standing stones. Two large, dragon-like creatures with black scales and burning red eyes glared at the confused alseids. One the ground lay the body of Riatha, deathly still. Terror and chaos followed as the creatures brought swift and sudden death, killing most of the alseid tribe members with razor-sharp teeth and deadly, black breath. The alseids that survived the inital, bloody attack fled into the forest. They counterattacked a few hours later, desperate to reclaim their grove and recover the body of their beloved leader, but the attempt was a fiasco and they were quickly driven off. Now, the few remaining alseids hide in the forest, frightened and unsure of what to do next.

Citadel of the Void Dragons is a void dragon lair suitable for four characters of 14th level. It is a logical sequel to Sky Stairs of Beldestan, but it can be played independently. The void dragon Astraxis and his mate, Yrsinestra, have long lived in an orbital citadel where the sky meets the void. This location allows the dragons to communicate with malign creatures of the void and still enables them to feast on the whales, cattle, and other large animals of the firmament below. This ready food supply is urgently needed right now, because the mated pair has recently laid a clutch of eggs. As a result, Astraxis is almost never at the lair—he is constantly on the hunt, bringing food to Yrsinestra and often sleeping on the earth below the citadel.

Their rivalry is coming to a head. When the PCs arrive at the White Worg homestead, they learn that the reaver dwarves are recovering from a recent attack.

"I was taken by the evil dogs while camping near Agav's bog. They dragged me into their lair, and it wasn't until I escaped that I knew the truth of the place: a great and bony wing buried in the side of a hill. They chained me in the dark with a candle made from foul wax and forced me to dig at the marrow. Their bonds were poorly made, and I fled several days later while they slept. What purpose did they have in mining that marrow? I cannot say..." The Marrow Mines are dug in and around the fossilized wing of an unnamed leviathan. A small pack of kobolds lives and works in the mines, which are heavily trapped. The kobolds defend the area fiercely and patrol the region around the mine. At night, a handful of urds make aerial surveys of the territory. The urds live in the deep reaches of the wing's tips.

"The Alchemists' Guildhall" is a rusalka lair suitable for four or five 6th-level characters. This adventure can be completed in one session.

We saw it—don’t turn your heads. Up near Hilltop Crossroad and the temple. It walked south; the trees fell in its path. Even the moon hid. Gods help Father Dren . . .

The trouble began several weeks ago when a duergar excavation team went to work in a long-abandoned temple. Drawn to the temple by stories of riches and artifacts, the duergar hired several giants as laborers before cracking the temple’s sealed doors. The largest of the giants, a loathsome Thursir mutant named Huppo, used his acidic vomit to expedite tunneling into the temple’s collapsed hall of worship. Then, Huppo found the horn—an unusual instrument made from a single piece of stone, with a mouthpiece so intricate only a master carver could have made it. The horn became the giant’s obsession. Seeing only the horn’s potential sale value, the dwarves demanded Huppo turn it over to them, but Huppo refused. To force compliance, the dwarves stopped feeding the gluttonous brute, but Huppo had already found his own source of food; in deep areas of the temple, worms were chewing out of the rocks, and Huppo ate them by the fistful. He also played the horn. Then, after several days of blowing the horn and devouring the strange worms, Huppo released a belch so noxious the dwarves had no choice but to lock him in a sealed chamber and carefully consider their next move. The horn’s call, however, had caught the attention of passing nomadic orcs. They set up camp outside the temple entrance in the hope of finding the horn and its player. That’s the current situation at the temple: the giant refuses to stop blowing the horn and belching out deadly clouds of stomach gas; the dwarves are frightened and edgy while their leader is obsessed with malevolent whispers; orcs are threatening to overrun the place; and the population of worms grows steadily as something awakens deep in the stone beneath the sanctuary of belches.

"Temple of the Deep Ones" is the lair of a group of deep ones and their god, suitable for four or five 7th-level characters. This adventure can be finished in one session. Ship captains report that a mysterious island has surfaced in the middle of a heavily trafficked trade route. Worse, ships that venture too close to the island are assaulted by a terrible creature and its servants. The island is disrupting trade throughout this part of the world, and several ships have already been lost. Unbeknownst to those that know of the place, the island rises at the will of Shar-Ngolyeth, a long-lost deity also known as That Which Lurks Beneath the Waves. The island is populated by a cult of deep ones and the beasts they have subjugated in the name of their dark god. The creature responsible for sinking ships is an aspect of Shar-Ngolyeth, a kraken. It is not meant for combat encounters; it's largely a plot device in this encounter.
