Lyric discussion by soundsgood 

After listening to 2112 over and over for the past month or so, I have come to the conclusion that:

1) Yes our protagonist ends his own life. And this comes just as the Elder Race of Man is returning from light years away to reclaim their home planet (presumably our planet earth in the year 2112).

2) Despite the ending of our protagonist's life, this is an uplifting Grand Finale (as Neil Peart had once claimed he wanted for this story) as the Elder Race comes in with superior fire power and Assumes Control of All Planets of the Solar Federation.

Awesome stuff!

The twin moons reference makes me think it is not earth after all, but presumably these beings are our human descendants. The rest of what is written here, I think, is about right.

It is ironic that what our protagonist was hoping for comes to pass, just as he ends his life...
