Having worked a s an orthopedic clinic tech for several years and with a wife with spinal stenosis, I have the greatest respect for your wife's trials. Tell her I wish her well and hope someday there will be a way to remove her physical challenges.
I am intrigued in your character because someone else, without your empathy and insight, would find it easy to create a character like this into a 2D cardboard cutout stereotype. I suspect this character will be far more nuanced and "real" given your knowledge and background. While not a fan of "steam punk" itself I am now interested in seeing where you go with this fascinating member of virtual humanity.
Please keep us posted of your writings/creative efforts.
Gracias,
Glenn
