Lehran... he was one of the 4 great heroes to defeat the goddess Yune and seal her within the medallion. He is considered to practically be the father of the heron race, and his magic is only outclassed by the goddess herself. I would not be a match for him myself, and I am the greatest practitioner of lightning magic in Tellius.

He has been alive since before the time when the goddess was asleep, nearly 700 years ago, and he will likely live hundreds, if not thousands of years more.
