It's actually fairly interesting. I read through the pages of what exactly is a dragon and anatomically and biology wise all their statements and special things that make a dragon a dragon are correct.
Like theres an entire page dedicated to their eyes only and it describes not only their pupil, but that there actually is another pupil in that area, that can rotate 90 degrees in all directions, and it serves as a focus point.
also this is mandatory
