The Old Road
The community closest to the Sunless Citadel is a small town called Oakhurst.
It is a conventional, small, one-street town (almost more a large village), with a tavern/inn and a general store, a blacksmith who is conversant with making nails and horseshoes, and a cleric of Pelor who is healer and more than half midwife for the people (and livestock) of Oakhurst. The town is a focus for a local rural region filled with family farms and ranches, which all told contains around a thousand people. The countryside surrounding the town is a mix of farmland, stands of old-growth oak, and rocky downs.
The one remarkable circumstance surrounding the region is the healing fruit. Once a year, at midsummer, goblins from a local tribe infesting a nearby ruin will ransom a single piece of magical fruit. This fruit, apparently an apple of perfect hue, heals those who suffer from any disease or other ailment.
