While researching in the Briarstone library, Dora learned that the town was originally founded in the early 4000s by a congregation of psychopomp-worshiping homesteaders. They were soon joined by the Briarstone Witch, and tales attribute many good works to her and present her as a figure who helped the settlers survive their hard early years.
As the Briarstone Witch shared her occult knowledge with the townsfolk, she eventually came to lead them. Then in 4050 A.R., the report of Pharasmin inquisitors accused the people of Thrushmoor of engaging in “perverted rites in mockery of Pharasma.” Encouraged by the Witch, the people of Thrushmoor split from both the church and the national government.
When emissaries of the state marched to retake control of the town, they found the entire population had disappeared. Although a few gruesome stains marked buildings across the empty town, no other evidence of the people was ever found. The unsettling event became known as the Thrushmoor Vanishing.
In Chapter 33, Gull recounted there being a main street in Thrushmoor known as Market Street, and that an old abandoned mansion known as the Wailing House sat at its end.
In Chapter 36, the party got its first view of the settlement as they approached by water. In Chapter 37, they saw it by daylight: Tudor-style architecture mixed with extreme Gothic. Brown and gray buildings with absurdly tall steepled peaks on all roofs. Mostly two stories tall, dark.
