"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.
"Ruins of the Umbral Tower" is a shadow fey hunter lair suitable for four or five 8th-level characters. This adventure can be completed in a single session. The ruined Umbral Tower rests deep in the forest, in a marshy region avoided by all but songbirds. Long abandoned by its original occupant, the tower features a malfunctioning gate that connects this place and the Plane of Shadow. The site serves as a base for a group of shadow fey hunters and their entourage of hounds and guardians. The hunters used the gate to travel from their home plane, and they now attempt to bag as many trophies and as much loot as possible before returning home when the gate reactivates.
History states that Zobeck was reborn in blood 80 years ago, thanks in part to the creation of gearforged by a revolutionary coalition of workers and mages. Unfortunately, history has recorded only part of the truth, and the Praetors will do anything to make sure the rest remains buried.
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.
"The Hive" is a spawn of Arbeyach lair, also featuring giant termites and termite swarms, for five 6th-level characters. This adventure can be finished in one session. Several mounds in the Forsaken Hills are the dens of voracious termites that have added flesh to their diet to supplement dwindling wood supplies. At night, swarms of termites hunt and devour prey. 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. They dug out a cavern beneath the mound, and now use the termites to protect themselves and gather food while they complete a difficult ritual involving dozens of sacrifices. The final sacrifice is prepared and the spawn are finishing their ritual when the party arrives.

The loss of Skyreach Castle in Hoard of the Dragon Queen was a major setback to the Cult of the Dragon, but still only a setback. The cult is determined to retake the castle and claim Tiamat’s lost treasure buried in its frozen walls and cloudstuff vaults, but they aren’t the only ones. Blagothkus the cloud giant is still the master of Skyreach, and he has gone to the hall of his cousin Brunvild, ice lord of Uldoveld, for the resources to repair and reoccupy the castle.

Following the path carved through the jungle by the excavation team, the PCs find the temple and its secrets. In this moss-covered and dark adventure, the party explores an old temple, faces its verdant guardians, and finds the source of the strange disease.
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.

And what will you say when another thief tells you the only way to find a treasure is to become hunted by the Praetors? Dark dealings, my boys, and a knife in the guts might be the price. Whose guts? Might be yours if you cross the wrong one of the Nine. How much evil should be done for the greater good? How many sinful men should die to save a pure soul?
This is an adventure for four 6th to 7th level PC's that may be completed in a single session. The Untamed are a street gang in a busy city. A recent change in leadership has transformed the members from pickpockets and second-story thieves into kidnappers for an inter-dimensional aberration named Xlrieh'oc. Their hideout is now a strange and wicked factory, capable of extracting the firm essence from a person; the process leaves the victim partly ethereal and their form no longer casts a shadow. Although most victims die during the procedure, those who survive are conscripted into the gang. The extracted essence is crated and shipped to the aberration's home plane through a breach between worlds in the hideout's backroom.
