When a desperate call for help interrupts the holiday celebrations at the Bureau of Balance, Taako, Magnus and Merlea are sent out after their fourth target for deadly relic Reclaiming: a powerful transmutation stone, hidden somewhere in the depths of a floating arcane laboratory that’s home to the Doctors Maureen and Lucas Miller. An unknown menace has control of the stone and is using it to turn the lab into a virulent pink crystal that spreads to everything it touches. It’s only a matter of time before this sparkling disaster crash-lands, but in order to find the stone and save the whole planet from being King Midased, our heroes will have to fight their way through a gauntlet of rowdy robots and crystal golems, figure out if they can trust the evasive Lucas Miller, and solve the mystery of what, or who, has put them in peril, all before there’s no world left to save.
