All tremble in fear of the Archthieves, from the jinnborn tribes of the Dominion of the Wind Lords to the priests of Bastet in Nuria Natal.

An evil oracular being has taken up residence in a lonely valley. The only access to the valley is through a thick, dead wood whose shadows draw out foul memories from those who travel there. The oracle, Lurinax, has recently divined the season in which the world will end. This knowledge is greatly prized by many, so the evil fortune teller hides in his lair, protected by maddening winds and the souls of those he slew to obtain his knowledge.

Worse, ships that venture too close to the island are assaulted by a terrible creature and its servants.

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.

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.

Unfortunately, the latest set of donors has already entered the Blood Vaults, and are being prepared for the donation process…

"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.

Fane of Serpents is a titanoboa lair suitable for three to five 10th-level characters. A rocky butte covered with soaring ruins looms over the landscape.

It rises starkly above the surrounding area, with four terraced plateaus. Each level is covered with the ruins of many-columned halls in an architectural style unlike anything else in the area.

The people of Feycircle believed the fairy ring for which their town was named protected them from the encroaching sands of the Western Wastes. When the ring withered, they learned they were right. Feycircle’s dewflecked pastures and verdant forests succumbed to the Wastes in an instant. Feycircle sank deep into the sands and was soon occupied by a tribe of fanatical dust goblins, a herd of dogmoles, and the giant worms that caused the blight. The PCs may explore the keep—the only structure remaining in the dusty sinkhole now called the "Pit of the Dust Goblins." Inside the keep is an entrenched gatekeeper who can divulge that two children remain in town, imprisoned by the goblins. The dust goblins have summoned and imprisoned a selang—a shadow fey—inside the blighted fairy circle.

They swarm over victims in wooden carts and wagons, and bring the dismantled wood back to their mounds. Three spawn of Arbeyach, searching for a location to summon Ia'Affrat, Arbeyach's herald, discovered a mound filled with particularity nasty termites and used their vermin empathy to gain acceptance.

Long abandoned by its original occupant, the tower features a malfunctioning gate that connects this place and the Plane of Shadow.

A venom maw hydra lair suitable for four or five 10th-level characters. The Red Craw Marsh, so called because of the delicious and plentiful red crayfish that live in the area, is a boon to the nearby village. More than a few intrepid souls brave the swamp each season to collect the crayfish. They either sell the crayfish to local establishments or ship them to nearby cities, where they earn a good price as the crayfish is a delicacy among the wealthy. The villagers have established a tentative peace with a clan of trollkin that inhabit the swamp. The crayfish collectors pay a small fee to the trollkin, who allow them to ply their trade in the marsh without (much) interference. It is a tense but profitable relationship for all involved. A powerful creature has moved into the marsh, however, threatening the delicate balance. When a venom maw hydra decided to move to the area of the marsh between the human and trollkin villages, it brought along a number of creatures that worship and serve it. This hydra and its allies have killed some of the crayfish hunters and some of the trollkin. Each side, unfortunately, believes that the other has broken the truce, thus stirring up animosity and putting both groups on the verge of war.
