Into your hands has been thrust a great responsibility - 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!
