I actually sent Mark a drawing of that huge mirror array for this page, because text just wasn't cutting it for the description. A picture is worth a thousand words, even when that picture is my horrible, horrible scribbling.
Shortly the story is going to involve people doing dangerous and quite possibly insane things. And that's the best kind of things.
The description for the light well states that there are "hundreds" of mirrors in the array. Not to worry, there are at least 196 more than we can see just off panel a tiny bit. On an unrelated note, next time there will be new stuff in the fan art section for reals.
