Whirring Cogs had a happy and near ideal life as a mechanic at the Cloudsdale weather factory. He had his best friend, a good social life, a job that he loved, and time to take joy in flying. While he enjoyed socializing with mares, he had no interest in complicating his life with a relationship, and lived contentedly as a single stallion. Then a mad changeling queen dared to make plans to wrest control of Equestria from the alicorn princesses. It's a pity that she was his queen, and Cogs the changeling had his perfect life ruined.
This is a prequel to my story - "Change of Life" - and explores the events that led up to the beginning of that story, before his fateful encounter with Lavender Dreams.
