"Imagine your standard, Day-Bound workday. Now, simply flip the hours. Princess Luna awakens and meets with Princess Celestia in the Mornings, raises the Moon, commits her tasks, attends Night-Court, and rounds the day by greeting her recently-awoken sister, bedding as the sun rises. It's this routine you'll learn to match, as a Student of the Moon. I know you're used to being a Night Owl, but this is reintroducing a proper schedule, to what I assume was a free-form approach to 'sleep and eat whenever' lifestyle, right?" Arnon explains, trying to make it clear. Just liking to stay up late wasn't going to cut it here. This was a full night-shift of studentdom.
