Okay i'll take another shot at this. When Sephiroth and Cloud died on the battle field they didn't go back to the Earth through the lifestream, they ended up somewhere else where a fresh start is promised. (There's a bit of bad language in this fic)

R-rated for later chapters. Remus was depressed untill Severus shows up and sorts him out. Now Remus is getting his life back together and trying to help others do the same.
