Gabriel, a self-aware robot who's goal was to help and entertain chronically ill human children was a victim of unfortunate events that left him and his creator; his dear mother-figure, escape to the world of Equestria. Separated, alone, and afraid, the Royal Sisters, along with Twilight and her friends, aid their new visitor to adapt to the new environment he was thrust in as they gain his trust and create bonds, while searching for his 'mother' in the process.
