Each Codex is a small puzzle or challenge that the player has to complete in order to unlock the Codex and earn whatever's inside. The first one is simple, you just have to walk around in a circle. I've been working on the progress indicator for it. It doesn't grant anything yet, that will be next up. (Before I do that I'm going to fix up a slew of bugs to get ready for the February release.)
