The Dimensions War

A young girl named Kian lives in the Fourth Dimension. Her parents have always told her that she is allowed to portal herself into the Third, Second, and First Dimensions, but not any of the higher ones. This is a Law throughout the entire universe. If a person portals into a dimension of a higher level then the one they were born in, then their senses will be overwhelmed. This could kill them.

Kian chooses to go to the Third Dimension, but the portal she uses malfunctions. She ends up in the Fifth Dimension. Her senses are not disturbed at all, so she comes up with two theories. Is the government of the Dimensions doing something horrible in a higher Dimension that it doesn't want the lower Dimensions to find out about, or is she a sort of mutant that the natural laws of the universe do not apply to? Kian sets out on a quest to find out, and discovers a hidden secret that throws the Dimensions into chaos.
