Let nothing end the Feast by the River. Let the celebration of our enemy’s vanquishing ring out night and day for eternity. Let the bones of our enemies and our prey mingle below our feet. This is your time, our time, the best time. —Queen Gellao on the eve of her victory over the followers of Dur; decreed at the River’s Bend feast hall

While traveling through a jungle expanse, the party meet a trader named Smera with a strange tale. Turned away from a nearby outpost, the trader is now heading back to civilization. Curiosity leads the party to the outpost, which has been destroyed. A strange disease has taken the outpost’s inhabitants, who built the place in support of a scholarly excavation of a nearby temple ruin. 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.

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.

Sky Stairs of Beldestan is a vampire warlock lair suitable for four characters of 14th level. It can be a lead-in to Citadel of the Void Dragon, or it can be played independently. For as long as any dragon can remember, the stairs of Beldestan have been a site of pilgrimage, a direct route from dusty earth up to the heavens, where enormous creatures soar and carry sacrifices up to the gods. Its base is well known for the efficacy of the invocations offered there, but very few other than the most faithful dare venture up the stairs themselves: enormous eagles, howling winds, and various inimical undead make the stairs a place that few find congenial for long.

"Bloodwood of the Cruor Circle" is an alseid and blood hag lair suitable for four or five 10th-level characters. This adventure can be completed in a single session. The Cruor Circle, a coven of dark druids led by a blood hag, has taken over control of the local alseid herd with the power of the blood. Within the forest, those who do not make proper sacrifices are stalked by the alseids and taken to the Bloodwood. Within the Bloodwood, captives become blood sacrifices, empowering the creation of sap demons, blood ponds, and other twisted products of the dark druids.

"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.

"The Riverfront Rat Gang" is a ratfolk lair, also featuring wharflings and a doppelrat, designed for five 1st level characters. This adventure can be completed in one session. The old dockyards once served as the primary center of commerce in town. Years ago, political pressure from an influential merchant who wanted the docks to be loser to her business forced shipping concerns to move their docks upriver. The new facility accommodates larger ships, and the old docks fell into disuse. Talk of converting the property into a set of riverside shops died when a rat infestation proved to be an unsolvable problem. Thus, the old dockyards have been decaying for years. This situation suited a former thieves' guild member, a ratfolk rogue, named Matimer Creel. A botched robbery (for which Matimer blamed his accomplice) turned the guild against Matimer, who fled from certain death at the hands of the guild master. He hid out in the old dockyards, confident that not even guild members bothered to go there. From there he began to exact revenge against the guild by ruining its plans or stealing directly from it. He also befriended the rat population, thanks to a golden rat's tooth he acquired, and the vermin help with his schemes. A trio of rat-like wharflings and a doppelrat, washed up on the riverbank near the docks, have joined Matimer's retinue.

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. Legend describes it as a monument raised by an inhuman race that was wiped out centuries ago as retribution over foul practices. Locally, the spot is known as Titan’s Height. 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. Their age and strangeness alone are enough to generate fearful legends. The stories grow worse when travelers or livestock disappear near Titan’s Height, which they sometimes do.

"A Triangle in Shadows" is an umbral vampire lair suitable for a party of four 15th-level characters. Magic weapons are highly advised. This adventure can be completed in one session.

But one named Caragorn has fled the city after coming between the lovers Philadon and Zenobia. Philadon and Caragor, however, are secretly meeting at Caragorn's tower behind Zenobia's back. Zenobia suspects them of collusion, and is seeking out the two male umbral vampires to get revenge.
