Owl wants her narrator to clarify something.
Human eyes judge brightness on a logarithmic scale. The difference between an indoors classroom without windows, and standing outside in direct sunlight, might not intuitively seem like a huge deal. In both cases there's enough light to see and read by.
Owl does not play Pathfinder Second Edition, but in that game both an indoors classroom and an outdoors field would be "Bright Light."
But "indoors without windows" and "out of doors at all" is actually, for purposes which do not judge brightness on a logarithmic scale, a pretty huge difference!
A factor of one-hundred difference, or even a factor of one-thousand.
So Owl would like clarification on whether the narrator literally means "the sky is about as well illuminated as an indoors classroom without windows lit by slightly burnt plasma rods," and not something gentler like "as well illuminated as the sky at sunset, or on an overcast day."
