Am I the only one who thinks the line in Rogue World Asylum all the lyric sites have as "we have found the colored keys" may actually be "we have found ecologies"?
Seems to fit a lot better with what the song's pretty clearly about: In "our future in debris", the protagonists flee a dying Earth and search for a "rogue world" to colonize instead. "As we search for what to follow in the night" (some people refer to the lack of sunlight in interstellar space as perpetual night) and eventually resort to going outside the galaxy ("first the sun and now the stars are fading" behind us), the rest of humanity stays behind, trying to adapt by sealing itself off in arcologies or something ("and now they build another wall again"). Once "we have found ecologies" somewhere other than Earth, "in a rogue world we are free".
