Which is a table I literally just threw together in 5 minutes, so don't expect anything marvellous, but it serves to signify what I'd be aiming at. You'd just roll 3d10 and see what came up (in reality I'd make them d20 or d30 of course), re-rolling anything that didn't make sense. Thus, the results:
6, 8, 9: Vagrants searching for hohools (Hohools are a kind of monster).
2, 7, 7: Brigands worshipping a statue.
2, 2, 3: Brigands guarding rice.
What I like about such tables is that they demand that the DM (and players too) come up with some sort of narrative right from the start. Whey are the vagrants searching for hohools? What statue are the brigands worshipping? Why are brigands guarding rice, from what, and for who?
