My concept is a paralyzed man, for some childhood reasons, who have to use a wheelchair to move around. The extent of the paralysis I'm still considering, but I'm thinking of just the bottom half of his body. I mean my original idea that I have been writing on a fiction is a man with ALS and him advancing through different stages of the disease, but the two worlds are a little different, as one has advanced enough tech to let him talk almost normally. I thought that bringing the whole ALS thing may be a little inconvenient, so I think changing it would be a sound idea.
