Brother and sister are thrown into the multiverse after what seemed to be a simple business transaction at a con. The younger brother Jack has been thrown to lands far beyond Equestria as the Sith equivalent of wrath incarnate. Where rival noble houses vie for power over the other and the threat of conflict lies on the tips of royal tongues. The balance of power will shift dramatically at Jack’s arrival and either prosperity or total war will be the outcome.

Meanwhile, the elder sister Katy has landed right into the heart of Equestria as the hero of all monsters. Feared at first, Katy will quickly earn the trust and eventual friendship of Equestria’s ponies. Katy will join the Mane Six on their adventures and will even go on adventures of her own as her and her brother’s arrival sparks an awakening of ancient creatures and prophesies.

After adapting and discovering their newfound powers, what will become of them? What will they change and what will they not change in a world that was doing just fine before they were dropped into it? One thing is certain, both Undyne and a Lord of the Sith have come to Equestria and their young lives have forever changed.
