Mellistella, genius from birth, was born in the Queendom Citadel—the Queen of Hearts' seat of power. With distant blood ties to the Queen, she was picked out from a young age to be a future researcher for Queendom, and spent a childhood and teenhood honing her mind and skills at the Queen's University.
While some of her classmates crashed out under the immense stress, and others were accused of stealing secret data and then beheaded on dubious grounds, Melli lasted it out on the force of her rapturous interest in metaphysics, and was granted her professorship at thirty-one by Queen Gertelina herself (well, via Merse, the Six of Hearts).
However she was clearly too good—that is, too dangerous—to be kept close to the throne, so she was sent to a satellite research centre in the Barony of Spades, where she would helm the team stationed there. She had no trouble gaining a reputation among the strange townsfolk once she was there, and eventually caught the attention of the strait-laced Baroness Blackrain herself.
Not that she was there knowingly to court her, but Blackrain has a type, and that type is incomprehensibly intelligent women. Soon, Melli found herself receiving a most hallowed invitation to the Baroness' own manor. They fell in love at the first crossing of verbal swords. It wasn't long before they were together in earnest, though Blackrain—normally so irrationally wrathful—was content to let her wife continue to work at the research centre as she had before, seeing her only once every five days.
