Unlike her bunkmates, Aster has the great privilege of being able to travel between decks using the medical pass granted to her by Theo Smith.

She uses this privilege to be an informational hub for her people, healing them and acting as a source of news.

“You’re a smart one. You know as good as me and as good as Flick that there is no Promised Land. Matilda’s an orphan, a daughter of dead gods. But the Ancestors is real and their spirits are at work.”

These words are spoken by Flick’s great-meema. As we later learn, the Matilda is on no course set by its founders. A complete rerouting of her course 25 years ago has gone unnoticed by those in power, who are interested only in the nihilistic perpetuation of their own power for power’s sake.

Here, Flick’s caretaker poeticizes the condition in a single word, erring on the side of normalization.
