The eight reindeer of the apocalypse
(Book)

The team of commercial sorcerers at Dawson, Ahriman & Dawson can help with any metaphysical engineering project, large or small (though by definition they all tend to be pretty large). They can also create massive great puddles of chaos that might one day swallow up the entire universe. Take, for example, the decision to recruit a certain bearded fellow whose previous work experience mainly involves reindeer and jingle bells. It might have seemed like a good idea at the time, but is he really the best person to save the world from Tiamat the Destroyer, who has literally gone ballistic?
