Naga (also translated Narga), is a recurring character in the Fire Emblem series, but unlike Anna, and Jake, he never appears directly and is usually somewhat important to the plot.

Ankoku Ryū to Hikari no Tsurugi/Monshō no Nazo/Shadow Dragon
Naga was the leader of the Divine Dragon tribe of Manaketes who protect mankind from the Earth Dragons. After the Earth Dragons were sealed, he lived the rest of his life in peace, creating the sword Falchion and the Fire Emblem from his fangs, as well as having a daughter, Tiki. After his death, he in trusted Gotoh to watch over humanity in his place, and make sure his daughter did not go wild and destroy the world. In the remake, Fire Emblem: Shadow Dragon, the new addition Nagi is hinted to be a reincarnation of Naga, she gives Marth a weaker version of the Falchion to make up for the one he did not have, and her ending title in the Japanese version is "Divine Dragon King's Incarnation".

Seisen no Keifu/Thracia 776
Naga, taking the form of a young girl, was one of the dragons who blood bonded with the Twelve Crusaders during the Miracle of Darna specifically the Saint Heim, who would wield the tome named after him. Because of this, Prince Kurth, his daughter Diadora, Alvis and later two of Diadora's children, Yuria and Celice, carry Naga's blood.

Trivia
Although he is not mentioned in Path of Radiance or Radiant Dawn, Kurthnaga's name is a combination of his name and that of Prince Kurth's.
