The female player character in Dragon Quest II. "Moonbrook" is the only kingdom name who isn't changed in the english translations aside from a minor spelling change ("Moonbrooke").
Her name was random in the original game, chosen from a small pool of names.
She is first found by the party as a dog due to a curse. Part of the quest involves finding Ra's Mirror to break the curse and restore her human form. It's not uncommon to give her dog ears and tail in fanart as a nod to this event.
