So a few months before I got to drawing these particular pages, I figured out what the inside of the Whaleship would be, and drew out a cool infographic for my reference. But I never figured out the *colour scheme* inside, so I had to figure that out as I started colouring the elevator and interior.
And that's when I created these little faerie lights. They're not living, they're tiny robots that emit light (programable for brightness and colours!) that use a basic AI to light up a given space.
