This cover was made by me for a Fallout of Equestria spin-off called ‘Vivat, Littlepip!’ authored by a rather famous in narrow circles russian MLP fic-writer Hellfire.  
The entire story is based heavily on a FoE flash game ‘FoE: Remains’ by empalu. This is a damn good platformer which I fell in love with at first sight! ^^ I recommend all of you who love Fallout of Equestria universe to play this awesome game ‘cause it’s just plain epic! XD ( www.deviantart.com/empalu/art/FoE-Remains-version-0-7-762532751).  
I’d also liked to recommend you reading this fanfic (it’s honestly very well written) but unfortunately it only exists in Russian =( But anyway, if you know Russian or don’t mind reading it with a help of Google Translator, I’m leaving here a link to it: https://ficbook.net/readfic/7210974. Trust me, it’s a pretty good story retelling the flash game’s plot with some interesting original supplementations))
