T1: You come to Hommlet to discover if this is indeed a place for adventurers to make their fortunes. (Bandits have begun to ride the roads again; Hommlet worried to the Viscount; this information has been spread through the countryside and the news has attracted outsiders to the village again).
Sounds about right.
The way my DM ran it, in about 1985, was that we'd heard of trouble in the area. I'm not sure if we had heard about the Battle of Emridy Fields and about trouble at the Moathouse before we started, or not.
