Nothing to note here.
Just gotta point something out because I’m pedantic: “calmest air within a 1 million light years in diameter” indicates to me that there is a circle with a diameter of 1 million lightyears, which means that the radius of this circle is 500,000 LY in diameter, meaning that there is no calmer area of the sea within a range of 500,000 LY of the Eternal Voyager. This sentence is midly confusing.
“Quantum Reef Domain” or “Quantum Rift Domain”?
If its not a train, then don’t call it a train. Maybe use a word from another language to signify that its something unique. Just adding a strange descriptor to the front of the word just makes it sound weird. Correction: it’s just that I’m used to cliches, and X Train / X Car / X Plane / X Ship is heavily cliched and I’m slightly annoyed. Clarification: this is a rant, please ignore.
Why do you do this? Just call them trains. A train is a train no matter what its made of or what rail it tuns on.
