Equestria is in the middle of a nightmare, between the ruler Celestia and her rebelling sister Luna. Metyllisk, G.A.A and head of the PROTOMAK divisions, is the only one who can help end the war. As much as he wants to fight without help, one of his proteges, Rainbow-347, birth name Rainbow Dash, softens him enough to have him swallow his pride and get some help from her.
This story follows these two ponies as their own hooves weave the threads of fate for a war-razed Equestria... but at the ultimate price...
