None know from where the Heresiarch first came, but all remember the night that it did. It rode down from the bleeding stars on a great serpent, hurling bolts of obsidian lightning that shattered the monuments and capitols of every nation. Its infernal army swept aside the defenses of the mortal empires in a single hour, decimating legions once thought to be the invincible fist of humanity's god-kings. Faceless priests - each bearing the symbol of the trident - drifted through the fallen cities and scorched villages on a frigid wind, and when they rose to greet the huddled men and women ringed by their festering, bloated dead, they spoke a single, simple offer: worship the Heresiarch or die. Thousands of crusaders fell tonight so that you might be given this chance. In a last stand that, for the first time, united all of the empires of humanity as brothers and sisters, a way was cleared into an infernal stronghold said to contain a gate to the Heresiarch’s fane. All is silent save for the clangor of distant battle. Surrounded by grim-faced knights and teary-eyed peasants – their hands clasped in desperate hope – you step through the glowing, churning doorway, knowing there will be no help and likely no return.

Deep under the ruins of Maure Castle lie the Chambers of Antiquities, vaults designed by ancient wizards to store magic items even they didn't quite understand. A continuation of last year's hit "Maure Castle." This adventure is set under the infamous ruins of Maure Castle, a monolithic edifice of night-black granite built by a powerful family of wizards. The Maures sealed themselves into the dungeons below their castle long ago, and today these dungeons have become one of the most infamous adventuring sites in the land.

This adventure presents one of those dungeon levels in detail. Pgs. 76-101

It begins in the marketplace or main square of a town when the calm, peaceful day is interrupted by a hulking golem trouncing through town, smashing objects, and attacking townsfolk. The party witnessing this should intervene and stop the rampaging golem with combat or by luring it into a nearby warehouse to trap it so it can be damaged and, eventually, destroyed by the town guards. When the party examines the golem’s remains, they find bones encased in the metal armor and the name 'Quartztoil' written in gnomish script. The town guard explain that this is the eighth construct they have encountered in the area in the past six months. The party can then go on to investigate the name 'Quartztoil', leading them to learn of an old, gnomish, aspiring artificer, Penaral Quartztoil, who had a lab and workshop in a tower in the nearby mountains, but who has not been heard from for close to a century.

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
