Sanctuary Bay is a small coastal town with a resort, a college, a night street and a great many doors nobody talks about. Beyond it lie the mountains, the moor, and the demesnes — whole worlds behind doors that should not open.
The day doesn't run on hours. It moves through four named phases, and the town rearranges itself around them — who's out, what's open, and what's willing to be seen.
Eight factions are tracked in the codex, and several more move through the story without ever filing paperwork.
