If anything, I'd start with everything that's been already established. She's a cursed 9:1 platinum/demonic silver alloy clockwork wind-up Living Doll that you won at Rep's betting pool. She certainly seems creepy at first, but who knows what she'll turn out to be, given how the MGE setting works.

Despite being clockwork, she doesn't actually need to be wound. Also, she'll automatically and rapidly regenerate from any damage she sustains due to her curse.

Apparently, Sebyl enjoys her company.

The idea of her conception was simple: Rep started hosting a betting pool, so I, being the epic-level prankster I am, smithed her parts and built her, dressed her up, cursed her with high concentrations of DE, named her Anastasia, informed her that the winner of the betting pool would be her husband and bet her on something unlikely to win. You, being the winner, ended up with her and your small mountain of loot.

That's all that seems set in stone (I have my head canon set on that name). Pretty much, anything else is up to you, since she'll be with you from now on.

Any other bits of info I can help with? ( =w=)/
