Guardians from the Octave above

[Unbound]

I basically imagine the 8th to be the same as the 1st of the next octave, in that they cannot be describe in any fashion as being separate. Each octave must bridge and so a gradient must eventually move to a balance. We unite in 7th, yet we then move in to the 8th which is also the 1st of the next and so this would be a platform between these two particular octaves. So we see our direct path.
