The proprietor of the junk shop known as Diamond City Surplus, Myrna is a gifted tinkerer with a penchant for restoring old robots. She suffers from a strong paranoia of synths, and as result is an outspoken anti-Institute conspiracy theorist. She is highly suspicious of synths shopping at her store, let alone browsing her merchandise. Myrna has a known habit of periodically accusing her customers of being synths while behind the counter, leading them to leave in frustration.
