Coral was the owner[verification overdue] of the Electrical Hobbyist's club in Boston. She had a son, who she left with an unnamed woman to look after. She locked herself in the building and would not respond to anybody. Her son and the woman came to the building multiple times, attempting to convince her to leave the building and meet them at camp. However, they heard nothing from her. Her son and the woman then left for the final time, never to return.
Coral is only mentioned in Fallout 4.
