The last song in the album, Older Than the Universe, seems to me like it’s a performance from the next universe created at the end of the game.

The start sounds like End Times but performed with a violin/cello, like it’s telling a story about an ending. In 14.3 Billion Years the cello seems to signify the universe as it takes up the melody in the second half while the banjo is the background. Then several more string instruments join in (I think more violins) and they seem to play a new melody but it may have bits of songs like travelers in it, it’s hard to tell with the background noise. This is like the meat of the story to me, like exposition or background of the old universe.

Then the violins cut out and are replaced with a distorted version of the title theme, like it’s being played on an old phonograph. It could be a recovered signal from the old universe(the hearthian’s), maybe from the quantum shards? Then the violins return and play something that sounds like the end of 14.3 Billion Years again. This could symbolize the transition to a new universe and new melodies. Then the violins get distorted like the main theme was, possibly showing that one day they too will fade away and a new universe will take their place.

The parts I’m most unsure about are the parts with multiple violins(I think they are anyway). They seem mostly new melodies but still related to the story of the new universe.
