Haha nah, the opening is in front, at the base of his neck

Ishidraan top to bottom is similar in scale to Africa, and Vaelis would be similar in size, if maybe a bit bigger than, modern China

Thank you! The rest of the layers follow a similar pattern to Dante's Inferno with some differences

The world kind of came together in pieces (first it was Ishidraan, then Vaelis, then the rest) so there wasn't really an inspiration other than I wanted to have a fantasy world that was mine. I think my favorite detail is either Fury's Spiral or Sunderborea
