So Eli... You said that there's no Morning or Afternoon here, what does that mean? said Eric.
First off Eric do not call me Eli, call me teacher or Teacher Eli, to be more formal and polite.
Eric sighed, alright, alright.. I'll be more polite.
Second off time isn't divided here like the way you are used to, there's only BTSS and ATSS.
What does that mean? said Eric.
BTSS means Before Twin Sun's Shine —which means there's only one sun out.
And ATSS which means After Twin Sun's Shine, it means there are two.
But teacher, when do we sleep? said Eric.
During BTSS. If only one sun is out that means it's night, though even then the sky never truly goes dark.
Oh? that's cool! said Eric with glimmer in his eyes.
