Freida

A straight-laced, worrywart of a character. She's the one always stressing about the group's safety, but no one takes her seriously.  Still, they're lucky to have her.

Name history: "Fretta" (surname) from "fret," because she's a worrier, became "Freta" (given name) as it started to click with me, and eventually became "Freida," as that was what I found myself calling her. Further irony, the name Freida means "peace, calm" or "peaceful ruler."
