In the parched desert sands, a mirage glistens invitingly on the horizon, but the nearest water is a hard day’s march in the opposite direction. You swear you smell the faint wet smell like coming rain when the wind shifts just right and see the stars reflected off some far lake at night. There’s no water here, just a lone sandblasted pillar, its features smeared by centuries of sand. Smell that? The brine of ocean mist? Here? Is the pillar made of coral polyps and mollusk shells? What is this place? An aquatic temple magically transported to an arid environment. Based on the author’s one-page map that was published in Knock #2 by Merry Mushmen. Published by Duvelman Dice.

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.

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.

A dungeon of tricky puzzles, ancient magical secrets, and more than a few lingering mysteries, designed to be played as a standalone adventure and not incorporated into another campaign. Six adventurers descend into the Temple of Mysteries to find a mystical artifact called the Strand of Tears. Seems straightforward enough, except that some of the party may not be who they say they are. In fact, none of the party may be who they say they are. Not only that, but they might not be who they don't say they are, either! Worst of all, they're trapped in the ruins of an underground temple specifically designed to keep people from proceeding unless they're proficient in puzzle-solving...and there may be doppelgangers on the loose.
