The Shadow Ship

The Chamber of Shadows
Located inside The Shadow Ship is The Chamber of Shadows that holds Lord Xashin along with the other eight tombs. The center of the room holds Xashin's tomb and located around his tomb are the remaining eight tombs which represent seven of The Shadow Riders and one of the White Knight's. The eight tombs surrounding Xashin form an octagon shape and are all magically sealed and shoot magic energy at Xashin's tomb which keeps access to his tomb sealed. Whenever a Target is killed, one of the eight tombs will open and the magic energy being shot at Xashin's tomb will disappear. Once all eight of the outer tombs are opened, there will be no magic energy holding Xashin's tomb sealed, thus allowing access to his tomb. When the Target that is matched with Xashin is killed, Xashin's tomb will open. .

History
After The Battle of the Kingdoms, Xashin along with Seth and 7 members of The Shadow Riders were sealed in tombs and placed on the Shadow Ship. The Shadow Ship was then launched out of Edenia and into space somewhere far away.
