@Alavil, that's exactly my thought too. I like to see the entire album as a story, but I fail to use some of the pieces. Connect Event Horizon with Elysium (the song) and you get a cool story about heaven (or a heaven-like Earth) though.
What do you think about song meaning? This computer voice, lyrics ("Deep in the dark, somewhere in space"), title (event horizon is a place in a black hole in the space) and cover of the album (fallen spacecraft from Polaris) suggest me the story of Polaris spacecraft being lost in the space and then falling to Earth. Maybe it's a stupid idea, but I like to imagine stories of things that inspired me in some way (in that case - Polaris and Elysium covers are bringing to mind some kind of story).
