I had attempted to tell the story of his clan's demise and his motivations through individual objects and equipment. For instance the emotions he feels when seeing his dead father's helmet, or the fact that all that is left of his clan is inside of that ship, and finally the reasons why his clan was destroyed through exploring his religious beliefs. This is a story about Vaat's road to redemption in the face of adversity.
Whether or not I succeeded at this is a completely different matter and if I can come up with smoother and less hidden symbolism, I will make edits as the app hasn't been up for even 30 minutes yet.
