When you were a foal you ended up with front row seats to a momentous event. Unfortunately that same event caused you brain damage enough that to this day you can't keep both your eyes open for long and the one eye that can see perfectly fine is unable to process color anymore.

Freshly broken up with yet another mare you return to the place that cost you your sight with little going for you other than being a weather Pegasus. Your boss as it turns out would be the last pony anypony would expect you to get along with at first. But since she doesn't know and you long since forgave her it should be fine... at least until she decides you're her newest prank victim.

(AN: I'm considering putting Derpy in here but not sure yet. Also after the first few chapters updates will be PAINFULLY slow, at least while I'm working on my other stories. Fav at your own risk)
