Editing Sleepy Marines (section)

== [[Emperor's Nightmare]] Relations ==

While theoretically not dissimilar to the Emperor's Nightmare chapter, the Sleepy Marines are unlikely to know of these apparently kindred spirits.  The only actual marines who may be able to directly enter the Warp are the chapter's psychically active brethren (or chapter Librarians if any exist), and they appear to be distinctly linked to the worlds created on the edges of Warp space by mortal dreams, just like Explorers and Dream Warriors.  All other marines only enter the immaterial semi-dimensional space created by the Beacon(s), and realistically wouldn't leave the Mainframe's effects for any reason.  The Beacon seems to exist as a mobile area for the Sleepy Marines to enter; on the edges of Warp space, like a collective dream.  Plus, the false Warp Storm created by the beacon would screw with all but the best astral projectors.

Just as well, the Sleepy Marines would most likely never physically meet marines of the Emperor's Nightmare.  Neither chapter will relinquish their marines to the harsh universe by sending them on far-flung missions.
