When the fragments are placed on the blank board in the Grafton Pawn Shop, they combine to form a treasure map that reveals the location of Vault 79. Additionally, turning on the nearby blacklight will reveal a unique, instanced code to be entered on the keypad in the mysterious cave to enter an elevator leading to Vault 79. The individual map fragments belong to six different people: Wren, Barry, Finn, Jessica, Fernando and Constance.
- Wren's fragment - Inside Morgantown High School, on the second floor, next to a broken terminal in a classroom.
- Barry's fragment - Red Rocket Mega Stop, on a counter in a station to the southeast.
- Jessica's fragment - Haven Church, on a counter in a hallway.
- Finn's fragment - The General's Steakhouse, on the north end of the counter in the bar on the first floor.
- Constance's fragment - Uncanny Caverns, on a counter in the gift shop.
- Fernando's fragment - Inside the Mothman Museum, on the front desk next to the cash registers.
