Many of the lyrics reference stars, or the sky, or particularly looking up to the sky. What the links mean is more difficult, and where they fit into the story is anyone's guess... Currently, it seems as though there could be a link to some sort of spaceship or hypergalactic mech, or perhaps an interplanetary species.
Song Lyrics Relating to Stars and Skies
Could there be something that has fallen from the sky? Or could there be something in the sky that is noteworthy.
This could be a some sort of satellite that governs the air.
The "stars" could be meteors, as many lyrics make it sound as if the stars are falling from the sky.
