Despite what some may think, those in Zhentil Keep haven't forgotten about their orc troops in Phent. In public discussion in Zhentil Keep, the leaders of the Zhentilar, the military branch of Zhentil Keep, have confidently asserted that the orcs in Thesk are completely loyal to Zhentil Keep. They maintain that the orcs are just biding their time and building up trust among the citizens, until the appointed time when the word is given. In private, these same leaders are gravely concerned. The leaders didn't get to positions of command by being idiots, and they know that the orcs are treated well and accepted in Thesk, which is a rarity for them with the humans and humanoids of Faerûn in general. The leaders know that many of the orcs would be reluctant to destroy the source of this acceptance. But what if the orcs' chief god, Gruumsh, told them to? The Zhentilar turned to the Black Network and presented the problem. The Zhents knew what to do. The Zhents have dispatched a powerful cleric, a master of persuasion and deception, to pose as an orc prophet of Gruumsh and whip the orcs into a destructive frenzy. In addition, the Zhentilar have staged raids against human caravans by what look like orc warriors so that they can start antiorc sentiment among the population of Thesk. Twin Oaks is a tiny, sleepy little thorp located just within the sheltering eaves of a great forest. Home to an extended family clan of farmers and woodcutters, the community was founded within living memory and since its creation the inhabitants have known only peace and prosperity. But just as the gentle breezes of late summer can transform rapidly into the deadly storms of autumn, dark times have come suddenly to Twin Oaks, in the person of Deskryn, a vampire who finds himself on the run from deadly enemies. Just two nights ago, as the good folk of Twin Oaks prepared for the annual harvest, Deskryn’s castle home was invaded by an intrepid band of adventurers led by a noble paladin. Although the party did not achieve its goal of slaying the vampire himself, they managed to drive him from his lair and force him to flee into the night with only the barest fraction of his former resources in tow. Unfortunately for the good folk of Twin Oaks, theirs was the community onto which the 2 vampire stumbled first, and it is here that the fiends have taken refuge. The little settlement offers the displaced vampire all that he needs: shelter from the hateful light of the sun, a selection of new servants, and a supply of fresh mortal blood. Even in his current condition, Deskryn alone is more than a match for the nhabitants of the thorp; but his best hope of survival lies not in conquest, but in secrecy. He plans to hide in Twin Oaks until he believes it safe to leave; then, he can begin plotting his revenge on the hateful paladin and her compatriots who brought him to this lowly state. As for the citizens of the thorp, they are all but helpless in the face of this powerful enemy. The vampire has already slaked his unholy thirst on one of their number, and his minions have taken hostages to ensure that the inhabitants do as they are told. All the folk of Twin Oaks hope that Deskryn will take what he wants and then leave them in peace, but few of them believe that such hopes are realistic. Until Deskryn has satisfied himself that the coast is clear, Twin Oaks—and its people—belong to him.

Despite the bitter cold that reigns here nine months of the year, the Timberway Forest has long been a source of prosperity for civilized folk who live nearby. Many trappers and hunters spend the better part of the year within its borders, stockpiling furs and meat to trade in the frontier towns to the south, where they spend their winters. Most feel that the value of these commodities makes braving the Timberway Forest worth the risk. Recently, though, a small group of trappers and hunters has awakened a terrible new menace in the forest. Based in a remote hunter's abode called the Bluerock Lodge, they hunted the animals of the woods more out of a deep-seated desire to be cruel than a need to feed themselves. In particular, they focused their hateful attention on the local Timberway lion population. Timberway lions are rather small (more like leopards), but they are known for being lithe and wary. Still, the trappers had the advantage of intelligence and tools, and before long they had slaughtered the entire pride save for its leader. As the winter worsened and game grew ever more scarce, this last surviving lion began to starve. At that point, the darker forces of nature took notice, and the Timberway Forest gained a predator like no other. Frozen Whispers is a short D&D adventure for four 3rd-level player characters (PCs). The scenario is set mostly in and near a remote hunter’s lodge in a snowy forest. The scenario can be placed in any cold area of your campaign world that features a remote tract of woodland—a copse of trees near the arctic circle, a swath of taiga near the treeline on a high mountainside, or even a normally temperate forest caught in the grip of an unnaturally snowy winter. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

The entity known as Oreiax is a gruesome, stunted monstrosity born of ancient death.

In the ruins of Kiris Dahn, a human town, lies a 'Slaying Stone'. The stone is said to have the power to kill any foe, though the stone is consumed in the process. The party will venture into the ruins which are the home to an assortment of goblins, hobgoblins, and kobolds. However, a mercenary band of orcs have been hired (by a benefactor who is not met in the module) to search the ruins for the Stone, and the party must find it first. The party must use caution and stealth to move through the town without alerting the denizens or the mercenaries while searching strategic points around the abandoned town to find the Stone. Eventually, the party should find the stone under the protection of an indifferent Brass Dragon.

Trouble Cubed is a is a pseudo-adventure with three interesting gelatinous cube encounters. These three encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL5 to 7.
