Lyn, full name "Lyndis", is one of the lord characters in Fire Emblem.
Lyn was born and raised in the plains of Sacae, a land populated by nomads. Lyn's father was the chief of the nomad tribe, the Lorca, and her mother was the daughter of Marquess Caelin. Some months before the events of the game, the people of the Lorca tribe were killed by the Taliver Bandits, all of them except for Lyn. After that day, Lyn lived on the plains all by herself, until one day, she met a tactician who had collapsed in the plains. She brought the tactician into her house to help him recover (the tactcian's default gender is male, but this can be changed at the beginning of the game).
