Just Add Water is a sewer-based dungeon crawl that can be easily inserted into any adventure. All you need is a location with a sewer system and a reason for the party to explore it.
Introductory adventure included with the 1991 "Black Box" edition of D&D
This AD&D scenario is designed to be a humorous departure from regular adventuring. The "heroes" are a fellowship of monsters on a quest to recover a magical item for an orc chieftain whom they have displeased. Having lost the map given to them, they must gain entry to a frontier outpost - probably by sneaking through sewers - and recover the map from a locked safe in the commanders quarters. Once they again have the map, the monsters must travel overland to an abandoned elven witches' temple on the shore of a mountain lake, where they will find the object of their quest. Pgs. 23-32
"Orcs have returned to the once quiet border province of Blackmarch. The Bleak Tower and its meager garrison are all that stand against the tide. Their only hope lies in a ragtag band of adventurers willing to venture into the perilous maw of Ironwood Gorge..." "Ironwood Gorge is a fantasy role-playing adventure for 4-8 characters of levels 2-5, designed for older editions of the world's most popular fantasy role-playing game and its clones such as Labyrinth Lord and OSRIC. The material is also easily adaptable to any other class and level based fantasy role-playing game. Ironwood Gorge serves as part two in the Blackmarch sequence of adventures, but is built to function just as well as a one-off adventure, a drop-in-a-hex location for sandbox games, or as a kick start to a new campaign. The module includes keyed maps detailing both the Bleak Tower: a living, breathing refuge for adventurers; and Ironwood Gorge: a cave complex with over 100 keyed areas of traps, monsters and mayhem. The module is illustrated throughout with original artwork and includes appendices detailing new monsters, magic items, and spells. Whether you are looking for an out-sized adventure to usher the hardiest characters to the intermediate levels, or a fully-realized location to plunder for maps and ideas, Ironwood Gorge is a treasure from the old-school of gaming..."

Dungeon Masters Kit - Number 1 Palace of the Vampire Queen For three centuries the peasants of the Dwarvish island of Baylor have feared the raids of the Vampire Queen and her minions. Sweeping down at night from the palace in the shrowded peaks of the island, they range even further in their search for blood. And not only blood - the children of dwarf peasants often disappear if they are so unfortunate as to be out at night. Even the cities are no longer safe. The most recent victim was the Princess of Baylor, daughter of King Arman, who was taken in a midnight raid on the capitol city of At Toe within past weeks. King Arman has offered fabulous riches and land holdings with titles to the person or persons who can brave the stronghold of the Vampire Queen and return his daughter to him alive and well. But, in truth, he holds little hope. For even King Arman, Ruler of Baylor, Defeater of the Ten Orc Tribes, is afraid in his heart to face the Vampire Queen.

The battles of the Blood War have raged for longer than mortals have known life, the conflict's savagery and hatred fueling the dreams, desires and obsessions of the multiverse. One way or another, the war spills through all the layers of existence, and little escapes its influence. Some clashes have consequences that shake the Lower Planes. Others are far less meaningful - they're fought solely for the sake of violence and killing. "The Field of Nettles" is set in the aftermath of an especially pointless battle. The adventure rips the player characters from their comfortable lives and thrusts them into the Blood War full force. The goal is to cross one of the more infamous battlefields, seeing the scope and the power of the fighting - and hopefully coming away with a greater understanding of just how big the Blood War is. The adventure is designed for a party of 4-6 PCs of 5th-8th level. The characters don't get to save the multiverse, nor do they find the key to unlock the dark of any great secrets. But they might come to realize their importance (or lack of it) in the scheme of things. On the fickle borders of the planes, that can be worth almost as much.
Many of the local lords had gathered for a peace moot. A perfect opportunity for the demon-possessed Aeldrith Forkbeard to murder them all in cold blood.

To reach the safety of the Kingdom of Marshes they must traverse the depths of the forest, avoiding Northlander raiders and the strange creatures of the Witchwood. The adventure also takes the PCs into the Feywild, where time runs strangely and memories are fragile. Finally, they must face the chilling Gatekeeper guarding the Feywild portal that allows the PCs to return to the Material Plane. Into the Witchwood is a generic adventure suitable for use in the Moonshae Isles. The adventure includes a map of the area, three new creatures and a new legendary magic item, the Circle of the Forest God.

A shrewd, spell-using green dragon has taken over the deepest chamber of a limestone cave as his lair. The dragon has persuaded a tribe of troglodytes to live in the outer chambers as a sort of "protective buffer" in return for gifts of magical treasure.

The outer chambers of the cave are protected by the troglodytes, the beetles and centipedes the troglodytes raise as cattle, and wild creatures.
