Azure Wind was the best thief in Canterlot, and found himself recruited into the Secret Guard, an ancient order loyal to the princesses and tasked with protecting Equestria, by any means necessary. His typical solitary nature is changed upon entry to the Guard, and he becomes closer to those who befriend him. With the increasing danger of each mission, including deniable operations outside of Equestria's borders, he must learn to trust those around him as much as he trusts his own skill.
