Chroms retainer is Frederick. Frederick is overprotective and serious. Frederick is recently starting to trust Robin.

While out on patrol near Ylisse's border, Chrom and Lissa discover a stranger unconscious in the middle of a grass field. Helping them to their feet, the stranger thanks Chrom by name. When Chrom asks them how they know his name, the stranger cannot seem to recall and believes that they have amnesia. Though Frederick expresses wariness over their story, Chrom decides to believe in them and brings them up to speed. The stranger finally recalls their name and introduces themselves as Robin just as a nearby town is under attack by bandits. Chrom, Lissa, and Frederick quickly head over the town to rescue the townspeople with Robin in tow. Though concerned at first over their well-being, Robin reveals that they are adept at both combat and tactics. Under their guidance, the bandits are dispatched and, impressed by Robin's abilities, Chrom decides to recruit Robin into the Shepherds.

That night, Chrom and Lissa are attacked by foul creatures that appeared from a portal in the sky. Thanks to a timely intervention by a masked warrior claiming to be the Hero-King Marth, they are warned of potentially worse events to come. The creatures are coined as Risen and a combination of these and Plegia's threat to Ylisse forces Emmeryn to seek help from the northern neighboring country of Ferox to aid them in the conflict. Acting as her envoy, Chrom meets with one of the two Khans of Ferox, Flavia, who vows to aid Ylisse if Chrom can best her rival Khan, Basilio, in order to become the ruling Khan. At a tournament, Chrom acts as Flavia's champion while Basilio has Marth represent him. At the start of the duel, Chrom notices that Marth is wielding a sword that looks exactly like his Falchion and during their initial combat exchange, Marth's fighting style mirrors Chrom's. When he inquires who taught Marth swordplay, he answers that his father taught him. After an intense duel, Chrom emerges victorious, securing Flavia's position as leading Khan and giving him Feroxi support.

Upon returning to Ylisse, Maribelle, a fellow Shepherd, is captured by Plegian forces and used as a bargaining chip by the current king of Plegia, Gangrel, to get the Fire Emblem from Ylisse. When they refuse, Plegia officially declares war on Ylisse. That night, Emmeryn is nearly assassinated by a Plegian cult, the Grimleal; this is foiled thanks only to a warning by Marth, who is revealed to be a woman. Fearing for her safety, Chrom tries to escort Emmeryn away from Ylisstol only to have it be attacked shortly after leaving. Concerned for her subjects, Emmeryn returns to protect her citizens and attempt to parley with Gangrel. Before returning to the capitol, Emmeryn entrusts Chrom with the Fire Emblem. Upon her return, Emmeryn is captured by Gangrel and announces that she will be promptly executed, forcing Chrom and the Shepherds to invade Plegia in an attempt to rescue her.

Chrom and the Shepherds quickly rush to Plegia castle and siege the castle as her execution begins. When they near her execution pedestal, their plan to have the Phila and her squad secure Emmeryn fails when a last minute archer ambush kills Phila and her squad. Knowing that Chrom would recklessly continue to try and rescue her, Emmeryn plunges from her pedestal. Chrom can only rush towards to her in horror as she plummets and witnesses Emmeryn's death up close. Though Chrom vows immediate revenge against Gangrel, Robin forces Chrom to retreat and regroup.
