Outside the Wall: Leaving Eden

The world as people knew it ended several hundred years ago with the opening of rifts between the physical and spiritual realms. It didn't take long for a dark miasma to infect the world, changing normal life into twisted abominations.
Eden was the only place left unaffected. This was largely due to the efforts of Sylvia, a girl trapped between the two worlds, not quite a ghost, but not entirely a physical entity either.
A long time ago, she closed the rift for the region, earning the people's adoration and worship. Now, though, after being trapped in one place for a few hundred years, she's begun to wonder what life on the outside is really like.
