Purgatory, The Inbetween, Abaddon, The Realm, The Pocket, The Alcove, The Edge, The Boundary, World's Edge, Life's Edge, The Before, The Beneath, The State, The Underpass, Underpoint, The Shard, Grimshard, The Vestige, ??? I really like The Constant, but i forgot thats what the DST world is also called. Something like that, which makes the realm feel like a separate pocket of reality that is invisible to - yet omnipresent in - the lives of everyday mortals would be great.
