For about three months, the Institute of the Newest Technology has been working and the chief of this institution was a brilliant mare named Source Code. One day she is requested to report to Princess Luna's chamber after her work.
The said mare doesn't expect what's about to happen.

Okay, this is my first story with a non-canon character - it's with my OC named Source Code (she has a dark gray, or blackish fur, blue and teal striped mane and tail, and a breaker ( </> ) cutie mark.
You can find the art of it on Derpibooru (the first art of it was created by my former friend, but he drew this OC being a stallion, so there's a rule 63 tag as well)
