Wise rogues join the government, where their larceny has the cover of “legality” and the cash comes in heaps and piles from deceitful receipts and pocketed procurements rather than in small, bloodstained purses from breaking windows, scaling walls, and risking traps and long-fanged guard dogs. Wise rogues do not, by choice, go up against towering giants armed with clubs larger than the tallest rogue in the guild. Nor do they try to nick treasure from dragons without a group of powerful fellow adventurers behind them, who can hurl mighty spells, hack and hew toe to toe with an angry wyrm, heal the injured, and (when things go as they usually do), resurrect the dead. There are wise rogues, and then there are player characters. Emeralds of Highfang awaits them with open arms, offering special challenges and rewards to rogue characters—but as always, the prospects are much better for a party of adventurers from a variety of classes, with wide skills and experience, and of high level. Some might find that a broad base of experience is not only helpful, but essential for survival.
