*The dark month is not a real span of time. Rather, it is a place holder hypothesis to try and explain scientifically how the journey around the sun takes 364 days, when the calendar only holds 336. The days pass from Kuthona 28 to Abadius 1 seamlessly. Almost no one on Terra is aware of this issue.
