Roll 1d4-1 to determine how many chance rolls to make between each marked settlement. For example, a d4 roll of 4 means 3 chance rolls. In a highly populated part of the Forgotten Realms (or wherever your solo campaign is set), that means 3 rolls of a d100. For every one of these that is 20 or below (20% chance for a high density population area), you find one unmarked settlement. It might take you 4 days to travel from one marked settlement to another. Space out these chance rolls however you like. (Note: this means 3 chance rolls during your entire travel time between the two marked settlements. Not 3 chance rolls per day). Unmarked settlements will be villages, hamlets, stationed garrisons, forestry worker encampments and the like - nothing larger than that.
