Got guilds? Probably not. If you regularly play adventures for the World's Most Popular Roleplaying game, you're still leveling up and not knowing who your trainer is (if any), you're picking up adventures through rumors and strange people wandering up to you in a tavern, and your contacts for information are nonexistent. But if you're looking for a some medieval realism to inject into your fantasy, you'll want a guild. You'll want the guild to help train your adventurers. You'll want the guild to assign them tasks to do, and tell them of adventuring opportunities. They'll be there so your adventurers will find information. The Blackshire Mercenary Company does that, and more, an impressive breadth of useful "realistic" fantasy material in the background of your string of miscellaneous adventures. The depth of the material doesn't go beyond adventure seed level, and the stats are for OGL/d20/3.5/Pathfinder, but it's plenty for us gamemasters who know they want a guild, but don't know what to do next. The supplement has a history of the BMC, subplot seeds, hiring rates, guild membership benefits, vivid personalities, and a prestige class for BMC members. The authors intend to cover guilds for other classes as well, and I'm looking forward to it!
