The Approaching Swarm is a short adventure. The party can consist of any mix of classes, but it should include at least one character that is good in wilderness settings, such as a druid, ranger, or barbarian, and at least one cleric. The adventure takes place in a swampland that is near a small settlement. The characters have just arrived in the small settlement of Crivdall, which is a fort on the edge of a huge, dangerous swamp. In the dead of night, a small armada of monstrous vermin attacked the characters and their hosts, and the PCs may have spied a mysterious figure that controlled their actions.

The party is enlisted to assist the Righteous Host, an army formed as a last resort to defend the world against the monsters of Elemental Evil. The host is greatly outnumbered. Its leaders send the party on a series of missions, each of which will give the Righteous Host an edge in the great battle to come. This epic adventure ends with the final push against the forces of Elemental Evil in the Meadows, and the outcome is informed by how effective the party is in their missions... and whether they are willing to risk putting themselves in the front lines. If the Righteous Host loses, players may decide to travel to Hommlet or other nearby towns to defend them. Whether the host is successful or not, players can decide to follow many different plot threads: exploring the Temple of Elemental Evil, finding the lich Kell the Eldest's lair and destroying his phylactory, or following the will of Bitbaern's Shield and discovering historical sites that were previously lost.

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. The encounters vary the cube's encounter situation significantly, and the tactics needed to deal with them, such as by trapping a character with a portcullis between a cube and a pit trap, placing a cube half down a pit trap, and having the cube accidentally ingest a beneficial potion (such as spider climb).

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.

Side-Trek adventure When your PCs gain access to the teleport spell, their whole world changes. That simple spell opens up instantaneous, long-distance travel. No more long overland journeys or dangerous retreats through hostile territory. All it takes is clasped hands and a word from the wizard, and poof! The PCs are where they want to go. Except that it isn’t that simple, because teleport isn’t foolproof. The off-target teleports are a matter of scattering your PCs someplace else on the map and forcing them to get their bearings and make the long overland journey anyway. But this Side Trek focuses on the really intriguing column on the teleport chart: “similar area.”

Into the Forsaken Temple's Crypt is a short adventure for four 10th-level characters. The adventure takes place in a buried temple crypt, which has been sealed for centuries. Dungeon Masters can adjust it for higher-level characters by expanding the dead magic areas and increasing the number and power of constructs and undead that inhabit the complex. Some things are best left untouched, and some secrets are best left untold. One such secret is the location of the resting place of the traitor Ellowyn Blacktree. Her body has lain undisturbed for centuries, undead but immobile, in the prison the elves created for her. The elven histories tell that Ellowyn was a powerful wizard back in a time beyond human reckoning. While others worked diligently to learn magic, Ellowyn's arcane powers came to her quickly. In her youth, she called this a blessing from Corellon Larethian, and she worked diligently to serve him for the good of all elvenkind. In time, she became one of seven female elves entrusted with the care of a mythal, or elven place of power, devoted to preserving the balance of magic and nature. But Ellowyn, it is said, kept a terrible secret of her own: She had fallen in love with a drow whom history knows as Orith To'rellen. One dark winter night she betrayed her sisters, Corellon, and all of elvenkind by allowing Orith and the followers of Lolth to overrun and defile the mythal. Ellowyn herself was then betrayed by the drow, who abandoned her on the surface near a vampire's lair as they returned to their home in the Underdark, leaving her to face certain death and elven justice alone. In the depths of their grief and anger, the elves sentenced Ellowyn, perhaps unwisely, to dwell forever in the darkness that she had chosen, thus ensuring that she never followed the normal path of life and death that most elves take. Many elves died at her hands before they could restrain her. With terrible spells rarely seen even in that ancient time, they bound her in an underground crypt far away from any living thing. There, the legends say, she waits, nursing a terrible hatred against elves, drow, Corellon, Lolth, and especially Orith To'rellen.

Every fifty years, a pair of storm titans met to pray in an isolated and well guarded cloud temple. This time, they have obtained a copy of the fabled Ritual of the Primordial Gate and are exploring its secrets in hopes of bringing a lost primordial to the world. Divine messengers are sent to the PCs to enlist their aid in disrupting the storm titans’ efforts.

The Bloody Maul of Kord is a magic weapon protected by the priests of Kord, who occasionally allow a noteworthy hero to use it when going on a dangerous quest worthy of the storm deity’s blessing. Six months ago, Atrimos of Ardor took the Bloody Maul for a quest to the Caverns of Demise, hoping to end attacks to the realm being launched from the caverns. He never returned. Now, the clerics of Kord hire the PCs to go into the caverns to retrieve the Bloody Maul of Kord—and to find Atrimos, if possible. Pgs. 108-113

Wicked forces conspire to usurp the power of the Raven Queen, god of death, by unraveling the foundations of reality. To prevent this cosmic coup, mighty heroes must survive an epic journey into the Shadowfell's timeless core, where all things find their end. The beginning of the end of the original 4th edition adventure path (although ties are very light to the heroic and elite tier adventures). The PCs must first prove themselves worthy to act as the Raven Queen's agents. They will then be sent to Death's Reach, a graveyard and dumping ground from the Dawn's War. There, they must fight through the Black Star Host- powerful elemental beings, to prevent Orcus was resurrecting a primordial, Timesus the Black Star.

The adventure begins with the characters discovering the recently murdered Returned, Varyas, and confronting his killers. Varyas's gold mask bears a code on it, one that points toward the sage Khea who lives in the nearby polis. When the characters investigate, they learn from Khea that the writing is undecipherable except for the first line, which refers to the legendary Court of Orestes, a site sacred to the god Phenax. She also notes that a recent earthquake has uncovered a cave along the Khystonos River that could be the secret site's location. If so, then perhaps within lies the key to deciphering the mask, along with its own treasures. With the information provided by Khea, the adventurers set forth into the wilds, where they'll face multiple storied dangers before reaching the Court of Orestes. Once at the lost holy site, the characters discover ancient guardians, as well as an unliving entity with the potential to reveal Phenax's lost secret.
