Maclir

"Chris, become Altea's sword. Aquire unbreakable power and loyalty."

- As My Unit told him during with Jagen in the base conversation.

Maclir is an implied character in Fire Emblem: Shin Monshō no Nazo ~Hikari to Kage no Eiyū~. He is the grandfather of My Unit that My Unit first mentioned during in the beginning of the game. His name was mentioned in the base conversation in Prologue VI with Jagen that he is a former Altean Knight from the front on the lines due to his injury, but his loyalty to Altea was unmatched and an old friend of Jagen. Maclir taught My Unit how to fight sometime before the beginning of the story and My Unit was able to join the Altea for his grandfather.
