I loved the sample chapters and cant wait for the book!
Did anyone else think of The Warp (Warhammer 40k) when Shadesmar was explained? If fast travel is possible through Shadesmar then they are two takes on the same idea, with Shadesmar being the much nicer place. With that being said if Spern are ideals given life than I would not want to meet, Death, Fear, Anger or a number of other Spern in Shadesmar.
