Chapter 489

The next morning is much more organized. Everyone knows their spots, and who was sitting near them yesterday, so they naturally gather in groups to enter the meeting hall at first light. Today the Elders are already assembled, the meeting won't be waiting on them, only the official start of the meeting. 

There is a series of windows high up the spire atop the building, with mirrors next to them. When the sun enters the window and shines on the mirror, illuminating the Council table, the meeting begins. When the sun leaves the mirrors for the final time, the meeting is over, and it is officially dark out.

It's not that they don't have clocks, but according to Waia they got annoyed at an argument about the actual time at some point in the past and ended up altering the building to have a built-in official timekeeper.
