The Ministry of Arcane Science were the cause of many problems in the present day Wasteland, like the Alicorns that dot the land, with their radiation and magical mastery  
But there was something else.. something more, for every princess needs a royal guard
 
The Mutant Ponies may not have seen much of the wasteland, being locked away even during Littlepip’s first big adventure, but now they’re free, free to serve their Mutant Alicorn masters.. all but one, the first, some unlucky soul by the name of Kelp, his body bleached maroon unlike his olive drab and navy blue counterparts
 
All of their bodies are warped beyond measure, and their minds twisted, some more than others, all more than Kelp, the first of the Mutants and.. the last of the sane from that great hell below
