From the introduction
Your PCs have final emerged from the dungeon laden with loot prised from the clutches of their slain foes. Heroically returning to civilisation, they find a tavern, divide up their loot and relax. Then they ask "So what are the people like here, anyway?" At this point, the GM likely panics and either replies "nothing special" or improvises a series of similar, one‐dimensional (and ultimately forgettable) NPCs. (After all, most GMs have got barely enough time to prepare the next adventure; preparing dozens of NPCs the PCs might interact with is likely a long way down their "to do" list.)
So What’s the NPC Like, Anyway? banishes this problem! Within, you’ll find tables designed to enable the busy GM to quickly and simply create hundreds of memorable, rounded NPCs. With just a few dice rolls, the GM can generate an NPC’s notable physical traits, personality traits, mannerisms, current activity and profession, leaving him more time to concentrate on the adventure at hand!
