Lugh

Lugh is a playable character in Fire Emblem: The Binding Blade. He is the son of Nino and twin brother of Raigh. He considers Chad to be family as well.

Hailing from an orphanage of Araphen, Lugh grew up with Raigh and Chad after his mother had disappeared when he was just four years old, inheriting his magical talent from her. After witnessing Bern reduce his home to ashes, Lugh temporarily stayed in the Elimine Church, but then reunited with Chad on the battlefield and decided to join Roy's party to punish those who took part in the orphanage's destruction.

Having a personality the polar opposite of Raigh's and more like his mother, Lugh tends to be positive, polite, kind, and conscious of others, as many of his support conversations have him bringing baked goods.

While aware of being able to use magic, he does not know just how helpful it can be. Before, he simply thought it could only hurt people, and did not want to use it. He decided to go out onto the battlefield with Chad, but stayed silent and concealed as he did not want to burden others with protecting him.

While he has this strong aspect at his core, he can be bitter, as shown in his support conversations with Melady, as he reveals that he's deliberately staying angry at Bern so he can fight.
