A tribe of evil norkers led by a human illusionist threaten the town of Nolivari. The heroes must brave the wilderness, find Grakhirt's lair, and defeat him to ensure the safety of the local villagers. A straightforward dungeon crawl against lots of norkers! When do you get to see those guys in an adventure? Lots of monsters from the AD&D Monster Manual II as well.

During the Last War, the ancients deployed their war-skiff assault units from elevator platforms that now dot a sector of the wasteland like a ravaged forest of rusted steel stumps.

For centuries, Vecna-archmage, despotic tyrant, the most fearsome of all liches-has been nothing but fearful legend to the honest folk of Greyhawk. Once the supreme master of all undead sorcerers, even today his Hand and Eye are object of immense power. Now something evil is stirring in the lands around Greyhawk. The Hand and Eye of Vecna have been found-and Vecna wants them back. TSR 9309

The carcass of a gigantic sea monster is now a small dungeon... Gargantuel was a gigantic sea monster (a whale? a prehistoric serpent? the Kraken? Leviathan itself?). She used to roam the high seas, destroying ships and devouring everything. Some of the people she swallowed survived in her belly. One of them, the sailor Torsti Seppänen, actually managed to turn the place into a comfortable habitat. One day, Gargantuel passed away. Her body now lies out in the open, luring the carrion-eater, the curious, the foolish. Strange creatures and artifacts await in the mounds of decaying flesh, and the insane Torsti Seppänen will do everything to defend his “home” from intruders. Statted for Lamentations of the Flame Princess, usable with any OSR type game. Hosted by eldritchfields.blogspot.com

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 troglodytes cherish the useless bits of magic without realizing their modest worth. The outer chambers of the cave are protected by the troglodytes, the beetles and centipedes the troglodytes raise as cattle, and wild creatures. The green dragon uses traps, illusions and magical devices to protect his inner chamber. Wyrmhaven is the second dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

This adventure has a lighter tone but isn’t completely out of place in a serious campaign. The challenges include combat, puzzles, traps and a legendary monster; Jack, in a Box. Does the party need to find something that an evil (and possibly mad) mage may have secluded away in an extra-dimensional space, and ordered an evil Jack-in-the-box and his toy army to protect it at all costs? Well that’s convenient because that is exactly the kind of situation that "Trapped in the Toybox" can help you with. Alternatively maybe that Dragon fight went a little too well for your party, maybe this “cursed chest” could help teach them a little humility. This adventure is designed for 4 (1d6 + 1) adventurers of 8th level who are in possession of a sense of humour. The toybox was created by a chaotic yet playful wizard, in order to hide an enchanted amulet under the protection of Jack. The adventurers should find themselves trapped inside the toybox, and they're in Jack's world now. Jack is the master of this domain and protector of both the amulet he has been entrusted with and the only exit of the toybox. There are a number of ways the adventurers may have come to be inside this toybox, e.g., the toybox may be found as part of the adventurer's loot in a dungeon or dragon's hoard, upon investigation it drags the adventurers inside. Note: This module commemorates our first themed week of Reddit's /r/Monsteraday and ties together this week's monsters in a dungeon designed for four 8th level adventurers. https://www.reddit.com/r/1d6Adventurers/comments/61axk3/trapped_in_the_toybox_adventure_module/ Published by 1d6Adventures
