   Summary

   What started as a novelty box of cardboard matchsticks quickly became way more than just that, not entirely unlike a forest fire. In a multiverse where everything works just a little differently, there’s bound to be a ripple effect. One primarily consisting of shameless smut and unapologetically gorgeous characters, but a brand new story all the same.
