Born Lucas Thorn, to mother Jacqui Thorn and a no-good thievin' and-a cheatin' sonofagun father that skipped town when he and his brother Jonas were barely old enough to walk. Their father left them high and dry, in debt and halfway to California, right on the periphery of the hottest sections of the rail wars.
Mama Jacqui had a talent she passed down to her children for sticking her nose in to look out for the little guy. Though the Greenfields are rarely such, and Jackson Greenfield himself is larger-than-life by most accounts, when stood up next to Baron LaCroix and the full might of his army, just about anyone would cut a slight figure. After Greenfield had a bad run-in with Bayou Vermillion, Jacqui bailed him out by sanctifying the land on which he stood and preventing LaCroix's nastier friends from entering. In return, Greenfield paid her and her children's way all the way back home to New Orleans.
Unfortunately, her own home wasn't similarly protected. LaCroix sent a nasty patchwork creature after her. A tangled mess of limbs and ligament, by hook or by crook or by some foul hoodoo of the Baron, it wore the face of the man who'd fathered two children on her and left so long ago. In her shock, she could barely defend herself, only getting Lucas to safety prior to her own death. The rest of the family took him in, and realized soon that the family needed a new mambo of Ezili, without their own darling Jacqui to hold down the fort. With his own mother dead, he volunteered to take up her responsibilities his own damn self.
Lucas, now Lyza, took to skirts and blouses just fine. It didn't take long for her to take to the ways of the more feminine loa either. When Greenfield, a few years after her mother's passing, sent out a request for her to help him out with his family's plantation, Lyza was all too happy to respond on her late mother's behalf and seek another life beyond New Orleans.
