This used to take an entire manga studio.
I did it alone, with no illustrator experience.
Over 300+ panels. A full adult D&D inspired graphic novel. Production quality.
This is Crimson Aether, and I'm posting it below for free.
@jondelarroz It actually started as a campaign in a Japanese table top game similar to DnD, which was then written as the light novel above. The light novel was then adapted into the anime we all know and love!
