At the risk of a litany of "lurk Moar mundane", I'd still like to ask what this thread is about. I get the linking sigil, I see the 1 5 3 6 9 2 17 in the crossed squares varies from the pattern of 0's.
Code seems more likely than this being a sigil in and of itself, aside from Ellis. Forgive me if this is a stupid question, or something I should be able to figure out, but I'm stumped. Any hints?
