Lab

It's a place in the comic. It’s unknown where it is exactly located. The only thing we know of this location is that from the outside it seems to be a white structure with some windows. In the interior, we have only seen Fabian (E112) room, and another room with no context.

The characters we can see in here are R, and Fabian (E112). There are more characters who aren't introduced yet that may have an involvement later on in the comic, like Odd, Taylor, and Puzzle for example.

Dave and Thorn who were introduced in the old pages, are no longer canon to the story, and therefore won't be included in the new pages.
