*SPOILERS *

The trivia items below may give away important plot points. The book titles in the Expanse series bear cryptic names in reference to the events in their respective novels. In the first books, "Leviathan Wakes" it refers to the once dormant and powerful alien virus that has 'woken up' to wreak havoc on humanity.

The 'Scopuli' is likely named after both the scopuli cliffs on Mars' northern pole, and (which those same cliffs are named after) the 'sirenus scopuli', the islands on which the Sirens of Greek mythology lived. This is fitting, as the Sirens would lure sailors to the cliffs so as to wreck their ships. In The Expanse, the Scopuli lures the Canterbury with the song of Julie Mao's distress beacon which leads to the destruction of the Canterbury and the major subsequent narrative of the show and book series.
