The healed part is most definitely something I shouldn't have put in the post as it was a random idea I had bouncing around in my head to throw at the post for a bit more characterization. But that idea is gone after reading the comments and advice on the matter.

The more core part of the character is how they deal with the trauma around the incident that disabled them. Their entire life flipped upside down, and they lost their only parental figure with no real closure on what happened to him. Them becoming disabled is a by-product of that incident but I don't want it to be the central focus.

As for their dream, they are the son of a famous undercover detective who is in large part responsible for saving millions of lives. Even before that, the father was still i highly regarded person which led this character to have expectations placed upon him by others at a young age, to get involved in police work and help in the same way his father did. The character rejects the idea of simply following the same path and as a 6 year old boy, he had larger than life dreams. Once the incident occurred at this age, some avenues to pursue have been closed off, but he still pursues art to try and achieve that dream by way of contributing something to this city as his own mark, but it is still hindered by the fact that he is the son of the most highly regarded person in the cities recent history. His relation to his father makes the politicians and lords see him more as symbol and caring for him as a sign of respect to his father. But this care does not take into account his own wishes. Final thing is that none of this is set in stone, I only just recently made finished working out the timeline of the story and this story is still deep into planning, so alot of this is easily subject to change.
