This, this, oh my god this.
Thinking about this, I don't think that the painter option would be an especially good option, simply because the story gets somewhat action oriented later down the road. I think another idea could be a robot or an android (going for a somewhat Science Fantasy
story) that has become outdated by something more technically advanced. In that sense, the robot in question has fallen behind in technological advancement. Or, perhaps this same robot is part of some Lost Technology
, and has lost its original purpose when its creators vanished? The society around the robot has fallen into obscurity, and it becomes its mission to try to bring this society's culture back into the light. While it's not quite failing its duty or purpose, it still fits into the theme of my story.
Thank you all for the ideas, by the way! I think I've gotten over my hump as far as creating a character has gone. I don't think I'll be able to use all of these ideas for major characters, but I'll certainly keep them in mind if I need anything in the future. You guys are great!
