Dalvin is a playable character from Fire Emblem: Genealogy of the Holy War. He is Creidne's brother and one of the initial members of the Liberation Army led by Seliph. He is the substitute character of Ulster if Ayra is not paired up. Despite filling Ulster's role, he shares a unique conversation with Tristan if the latter waits adjacent to him after Melgen is seized. After declaring that he does not want to be on castle duty, Dalvin convinces Tristan to have dueling practice with him. This causes Dalvin to gain two points of strength and one point of skill and defense, while Tristan gains two points of strength and one point of speed and defense. This event can only occur if both of them are at Level 10 at the time.
