The Lowlands of Aldermoor
You reach the walled town of Oakhaven with 25 Money, a soaked cloak, and a winter ahead — in the harsh feudal Duchy of Aldermoor, where the town guards punish theft without hesitation, magic is distrusted, and a warm bed costs more than coin. Here sex is a common currency of survival: innkeepers, caravan guards, and nobles all trade it freely, and the desperate trade in the only thing they have left. Spend your 25 carefully, and decide what a night under a roof costs you.
