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.

"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.

"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.
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.
"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.
The Claret Wellspring is an adventure for four 4th-5th level PCs. "The first spell cast has not yet finished its work." Strange lights in the desert lead the PCs to a long-forgotten oasis. Travelling towards the lights, the PCs are threatened by magic so old, it defies categorization. Arriving at the withered shore of a blood-colored pool, the PCs discover an ancient dial and three tooth-like columns rising from the ground. Turning the dial results in the water being magically siphoned into the column's hollow cavities. If the pool is emptied, a small door is revealed in the crimson-stained much. They must defeat a blood-infused water elemental before proceeding. Once inside, the PCs share a room with a dark ritual running since the origin of the world. The keeper of the place, an immortal fey inside a powerful suit of armor, offers little explanation as to the nature of the ritual, and he seeks to ensure they tell no one of the Claret Wellspring.
