Judy is a member of the anti-Pirate squad that sets out in the Celestial Omnibus, and finds itself in trouble outside Arth. She has it harder than many of the rest of the squad, since the fighter she is having a conversation with at the time the trouble starts simply drops dead, with no warning and no sign of what had happened to her.
Judy is prostrate for some time, but eventually finds herself falling in love with one of her captors -- the upright Brother Edward, who is the head of Healing Horn. Luckily, he returns her regard. Most of the rest of the anti-Pirate group are a bit morally flexible, willing to do what it will take to defeat the pirates, but Judy is much more direct and innocent. So we find a good match has been made here.
