“You don't need to thank me, Ethlyn. You know Sigurd and I go way back. Not to mention that he's my brother-in-law now. Besides, I can't have you fighting alone.”
—Quan in Genealogy of the Holy War.
Quan (キュアン Kyuan, Cuan in the Japanese version) is a playable character from Fire Emblem: Genealogy of the Holy War. He is the prince of Leonster, the son of King Calf and Queen Alfiona, and a descendant of the Crusader Noba. He is Ethlyn's husband and Sigurd's brother-in-law. He is also the father of Altena and Leif. Alongside Sigurd and Eldigan, Quan trained at the Royal Academy of Belhalla prior to the events of the game.
Quan will receive the legendary lance Gáe Bolg from Ethlyn in Chapter 3, but the player will only be able to utilize the lance for a brief moment before he leaves in the preceding chapter.
Quan, alongside Ethlyn and a force of Leonster Knights, will meet his untimely end in an ambush by Travant while crossing the Yied Desert in an attempt to reinforce Sigurd's march on Belhalla in Chapter 5. This tragedy was later known as the Yied Massacre.
Quan lacks the Pursuit skill, but his base stats and stat growths are excellent, making him highly usable during ranked runs. Despite the fact that he will leave the army in Chapter 4, it is still highly recommended to train him, as he will, inevitably, pass on his stats to his children, Altena and Leif.
“Ethlyn: Quan! Are you okay? I hate to run on my brother, but we must get you home to recover. Quan: Sorry, Ethlyn...”

“Ethlyn... I'm sorry. Finn... Look after Leif...”

The Fire Emblem Treasure family tree reveals that Quan's father is King Calf and his mother is Queen Alfiona, who are both mentioned in Fire Emblem: Thracia 776 Illustrated Works.
