Chrolly

Chrolly is the het ship between Chrom and Sully from the Fire Emblem fandom.

Canon
Chrom and Sully are childhood friends. She is a tomboy cavalier, member from a noble family that served Ylisse as knights during generations, and Chrom is the prince of Ylisse and eventual Exalt. In their childhood they played together with sticks, swords and used to sneak out of town to climb trees. Both remember the old days as being good times. As adults, they use to train together and see each other as evenly matched.

Sully first joins Chrom's army in Chapter 1, when she arrives to help Chrom fight off an army of Risen. Chrom eventually confess to Sully that he is the only woman that he feels comfortable doing certain things like training and admitting his weaknesses. He also comforts Sully when she is insecure about not being girly like other ladies saying that she is perfect and that she shouldn't ever change. Eventually Chrom says to Sully that she is his anchor, which results on her bluntly asking him out and questioning if he likes her just as a friend or a if he sees her as a woman. The conversation ends with Sully making a marriage proposal in which Chrom accepts and gives Sully his family ring as an engagement gift.

Two years after the war against Gangrel was won, Sully marries Chrom and becomes queen of Ylisse, and together they have two daughters: Lucina and Kjelle. Lucina time travels after an apocalyptic future in which Chrom, Sully and all the shepherds are killed, resulting on the Kingdom of Ylisse being also destroyed. Sully finds Chrom hugging Lucina and gets furious thinking the young girl is the king's lover, to the point that she consider piercing both with her sword. After some sceptical moments, she quickly realizes that the one that her husband is holding is their daughter from the future after she recognizes the eye mark which only her new-born have. She possibly also encounter her other daughter Kjelle who time travelled together with her older sister, and together they decide to fight to change the future and save their kingdom.

Fanon
Sully is mostly accepted as one of the better, if not the best romantic conversation of Chrom, this happen because he is portrayed as being oblivious to love and a bit awkward with girls and his conversation with Sully flows naturally. Their relationship is also liked for the childhood friends romance aspect. There is also some fan who pair them because they want to make Sumia marry someone else than Chrom. However, she has gameplay disadvantage because she can't access the powerful gale-force skill, while all other mothers of Lucina have this ability to pass to their children. For this reason, Sully and Chrom is less popular than Chrobin, Chrolivia and Chromia, being in a steady 4th place of Chrom's most popular pairing. In fanfictions, the distaste of Sully for girly things is often used to explain Lucina being a fashion disaster, since Sully isn't interested in fashion and this characteristic would be passed to her daughters.
