Thorax has been living in the Crystal Empire for some time now and ponies are adjusting to the idea of living with a changeling. One day, on a walk with Sunburst, Thorax learns about the holiday Hearth's Warming and decides that he'll make a gift to show his thanks to the ponies that have made his new life possible - The Royal Family.
This is a collaboration I've been working on with theOwtcast for the past month or so, and is set in something of an AU to their story The Odd One (kind of like the timeline is set up that part of the story coincides with the holiday season). Big thanks to theOwtcast for their contributions, especially the artwork they made to feature in the story. I hope everyone reading this enjoys it, and Happy Holidays/Hearth's Warming!
