Clarksville

Clarksville was a pre-War city in West Virginia.

Background
Before the War, two adolescent girls known to have frequently played at a river near the city disappeared. The city's police department tried to silence the incident, though news still spread.

Behind the scenes
Clarksville appears to be a misnomer of Clarksburg, a city which appears in the Toxic Valley region of Appalachia. Picking up the note Unsolved: Missing girls which mentions Clarksville starts the quest Unsolved: Picnic Panic, which instead directs towards Clarksburg to investigate the missing Chelsea Wesley and Mary Tinley.

Appearances
Clarksville is mentioned only in the Fallout 76 update Wild Appalachia.
