From The Heretic Knowledge Vault
Molly is a childhood friend of player character Layla, with whom she shares origins in the town of Kugelheim (and in the Gewehr, which uses Kugelheim as a base of operations). The two young women hadn't seen each other in ages at the start of the game, as each got married and moved out of town, Layla to run the nascent Gewehr operation in Kiyoka (and give birth to son Zachary), Molly to join her rich husband on the opposite coast of Farrel, somewhere in the vicinity of Ysabel, get pregnant herself, and learn to pilot an airship, remarkably enough. It's her skill in the latter direction that leads her to help Layla on a reconnaissance mission in northern Farrel, during which the mother and the mother-to-be instantly re-establish their close friendship. Following various adventures, Molly and airship cruise back east as Layla settles into Rinkaiel to learn some magic.
We probably won't see her again unless the action in the game moves to Ysabel, but she's still out there, happily gestating away and probably getting into minor trouble with the airship )not for nothing did she gain the nickname "Typhoon Molly" as a girl).
