A pretty cool little calendar system, I really enjoy the thematic weaving in of law and chaos. I think more detail on what happens in a Glimmer, and maybe on weather/seasons generally, would have made it a bit more exciting, and given that the layout of the calendar itself is so simple you probably could have made a lot more use of the two pages.
Also I didn't understand what the beads were doing on the example calendar - I understood there'd only be a new bead every 30 days/1 Lune (or more/less if it's a black bead for a Glimmer), but in the example there are 6 beads alongside the 30 days shown. Or are the beads not related to the days/weeks they are placed next to, but just a tracker of when Glimmers happened over the course of the whole year?
