CM4 is part of a series, CM1-CM9, from 1984-1987, for upper-level ("Companion" tier) PCs.
This adventure is designed to fit into an advanced context of the PCs controlling territory, having claimed or received their own lands, a 'dominion' of their own, and as such includes the intrigue of engaging with adjacent nobility's lands and agendas.
One of the Weirdest Dungeons Ever: inside a 1280ft-tall gnomish robot. D&D is full of weird dungeons, but "Earthshaker!" lies near the top of the list, since it's set inside the huge, ancient Earthshaker machine.
Into your hands has been thrust a great responsibility: the management of a growing domain. It has been a hard winter. Now, with the coming of spring, the populace looks to you for leadership. It will take a careful and generous hand to restore your subjects' confidence.
But even as you hold your first courts of the new season, an ominous shadow falls across the land. Earthshaker - wonder of the world - has arrived! Will its arrival be a curse or a blessing? With bold action and skillful diplomacy, you may yet divert disaster. But if you fail, the consequences will certainly be the subject of many a minstrel's tragic songs for years to come!
"Earthshaker" includes a complete dominion setting, new player characters and NPCs, and complete material on one of the greatest marvels of the world - the giant and unstoppable Earthshaker!
