The fey in question is Tylia, a wyldfae nymph (exiled from Summer due to an offense to Titania a few centuries back). A few decades back, a focused practitioner-binder managed to catch her and bind her to his will; as a result, she spent the last 20+ years as the concubine/maid/cook/etc to this scumbag (and gaining a great deal of familiarity with household "ferromancy" in the process).
Now the PCs enter the picture; one of them, Gene, is dating the local Summer representative, a nymph named Melia. The PCs do what PCs do, and become annoying, so, the scumbag executes a series of distractions at the PCs, tailored to keep them occupied while he gets his plans finished (it worked, btw). Gene's distraction is Tylia-in-a-box. A large package is dropped off at his younger brother's apartment, where all of the Christmas presents are being accumulated, addressed to Gene, CO his brother Fade (Gene and Fade are nicknames; their actual names are pretentious as hell). Inside the box is an old fashioned steamer trunk. Inside the trunk is a Tylia whose memories of the last 20 years have been carefully removed. On the trunk itself is an enchantment that'll transfer the slavery-binding on Tylia to the first person who opens it.
If Gene had opened it, and Tylia had made him her master, that would have disrupted his relationship with Melia wonderfully (Her being the official Summer rep for the region, and Tylia being a Summer exile). As it was, with a few judicious compels, the younger brother opens it, and finds that he is now the... proud? owner of a beautiful woman.
After a few months of research, the wizard-PC figures out how to break the slavery-binding, and out of gratitude for his kindness, the debt owed for freeing her, and not really having anywhere else to go except back into the same exile that got her captured in the first place, Tylia decides to stick around and stay with Fade. Shortly, nature takes its course, and Gene is informed that he's acquiring a sister-in-law and uncle-hood.
The current scenario is the culmination of her personal arc, in a way; the PCs have been tracking down the binder, and have found him; where we ended last session, we were about to start a four-way battle royale, and Tylia is participating on their side--hence the major milestone.
So, we have a smart, house tech-savvy fey who has more links to the mortal world than the Nevernever and is pretty damn happy to have it that way, is shortly going to be acquiring a sur-name via mortal ritual, and has been dealing with a cautious, smitten young man who had been prefacing most of his statements with "What do you want?" (so as to avoid taking advantage of her while she was under the slavery-binding).
With that context, you can see why I'm considering positive refresh.
