Lyric discussion by Noah the Great 

Cover art for Fifteen pt 1 lyrics by Forward, Russia!

I think it means that they don't want to be what other humans have become, how the world has been so filled with shit.

"A truncation of Caeser's might We came, we saw, we set up our lives To beg, to cheat, to lie, to steal The parts of you that make up the forgotten sides"

I think that "We forget how to sing A skyline envelopes the east And western misfortune is freely erased " means that we rewrite history to suit us.
