“Some have used that name, yes. You must listen to me. As you suspect, Gharnef has made off with Falchion. With Imhullu and Falchion in the sorcerer's grasp, Dolhr now must think twice before challenging him. Gharnef knows this. And one day, he plans to conquer Dolhr and rule the entire world.”
—Gotoh to Marth in the end of Chapter 15 of Shadow Dragon
Gotoh (ガトー, Gato in the Japanese version) is a playable character from Fire Emblem: Ankoku Ryū to Hikari no Tsurugi and its remake. He is a member of the Divine Dragon Tribe and a bishop of great renown who is known as the White Sage.
Gotoh is one of the few Divine Dragons who survived the war against the Earth Dragons and lost the ability to transform into a dragon after discarding his Dragonstone. After Naga's death, Gotoh was commanded to guard humanity. When Medeus and Dolhr began their war against humanity, Gotoh led Anri to the Ice Dragon Temple, where Anri claimed the Falchion that was later used to defeat Medeus. Eventually, he founded the nation of Khadein and trained two pupils, Miloah and Gharnef, both of whom strived for justice. He chose Miloah to be his successor and gave the Aura spell to him because he had more empathy and compassion than Gharnef. Out of jealousy, Gharnef stole the Darksphere and used it to create the Imhullu tome, which resulted in his soul being twisted.
Ever since that incident, Gotoh has been observing Gharnef's actions, hoping that someone would eventually stop him. When Marth proves to be the person to do it, Gotoh begins assisting him in his quest by giving out advice. Late in the game, Gotoh points out Michalis's foolish behavior during their conversation. He also creates the Starlight tome, which is required to break through the barrier of Imhullu, by using the Lightsphere and the Starsphere that Marth brings to him.
In Fire Emblem: Mystery of the Emblem and its remake, Gotoh continues to serve the role of an advisor to Marth, although he never becomes playable. He gives the Lightsphere to Marth as well as the Starsphere if all twelve of its shards have been collected. He also allows Tiki to leave the Ice Dragon Temple with Marth in this scenario, but he forces her to continue sleeping otherwise. This is to prevent her from becoming feral.
“The end...was so close...”

At Nyna’s request, Gotoh became archmage of Akaneia. The world never knew a better teacher.
