Merric

Merric is a playable character from the Archanea Series of Fire Emblem. Called the Wind Mage for the tome of Excalibur that he wields as his weapon of choice during the War of Shadows, Merric is an Altean noble who studies magic in Khadein under the tutelage of Wendell. He is also known to have grown up alongside the royal siblings Prince Marth and Princess Elice, the latter of whom he is in love with.

Merric's appearance clearly resembles, and possibly inspired, the overall design for Mages appearing across the Fire Emblem Series.
