A group of Bandits finishes a transaction and finds something not belonging in the Zone

(a story ive had in mind since 2013 and it has been reworked and rewritten every once in a while and now ive finally let it be a story to publish if it gets liked i continue it otherwise it gets abandoned.)
(just want this story out of my mind since i always wanted to make a S.T.A.L.K.E.R story in which Fluttershy appears and meets mutants and tries to find a way home)
