One year after taking up the role of the Gatekeeper, guarding all rifts in and out of his dimension, Jason Watts discovers something new. Someone has built a version of his original machine that will cross dimensions, but only if they are parallel. Normally, this wouldn't be a problem.
But Jason is soon faced with an enemy who has powers beyond that of anyone from his world. These creatures threaten the existence of all life.
But how could they come from a land filled with magical ponies?
