Mines of Paldemar
I think on the edges of human town, little girl took interest. Andochas sorta acted as a grandparent to the girl then one day the girl is in Andochas’s shop while he’s working and he didn’t realize it. Something goes haywire maybe explodes and maybe shrapnel gets in her spine and paralyzes her from the legs down. He built her a wheelchair but wants to return her ability to walk to her. He sends her gifts so she knows he’s still alive and still working on solving the problem. He lived at the edges of a small town (need name). Little girl’s name is Rose. Andochas obsesses about fixing the weakness of the flesh. Has ideas for automated legs for the girl but better yet would be to give her a new body that was completely impervious to harm. This is of course an improbable idea at best.
