   Summary

   Captain Tuurok Castar of the Marines Malevolent has just received a crash course on why you do NOT mess with ponykind... in both the present, and a dark future that must not be.

   A Conversion Bureau/Warhammer crossover with a Cosmic Horror spin. Also a Grimdark brutalization fic... in which the ponies are the ones doing the brutalizing.
