The Long Between is an original song from the TrueDark Rising world. It belongs to the stretches of road between Keepers -- the unnamed days when the Kinsfolk walked without a teacher ahead or a home behind.
The song carries the full weight of the Wandering. Each verse marks a different stage: the early confidence of walking in Eyru's open hand, the growing strangeness of the land, the tools that changed their gait, and the realization that every light they carried hollowed a shadow deeper in its place. The chorus repeats the only hope they had -- that there is a Keeper further still, beyond the ridge, beyond the hill. They walked because they were not yet done. Because the night still feared the sun.
By the final verse, hope has thinned but not broken. They planned a place to stay by day, but by night their bearings slipped away. Still, each Keeper's name, spoken softly and passed along, was a spark -- not Eyru's light, but enough to prove them wrong about giving up. The Long Between remembers that the hardest part of the Wandering was not the darkness. It was the walking.
Like all songs of this world, it serves as memory. It is meant to be sung on the march, and understood fully only in hindsight.
