So, I was rereading the Heroes of Olympus series and I started wondering how tall everyone was in comparison for each other. I decided to draw a picture of the seven (plus Nico and Reyna) later on, and so I ended up needing this information. I If you can provide estimates of each character's height that'd be great. Comparison excerpts (from Heroes of Olympus, Magnus Chase, or Trials of Apollo) would also be a great help. It might also help to show age so I can figure out proportions.
