As the group settles down to sleep, Little Oracle explains to the agudners their Sieg tribal belief surrounding sleep. It appears that they give meaning to multiple elements, both spiritual and physical.
Little Oracle mentions the “real eyelids” which are closed first when trailing off to slumber. They then go on to mention their heart entering a trance-like state, floating away into the darkness until their inner “spiritual eyelids” close for them as well.
The moment of time when this occurs are described as belonging to their god, and the manner in which they close is unbeknownst to them, only to the aforementioned deity. As such, the machinations behind the act of sleeping remain a mystery to the sergals, giving way to deep spiritual implications.
