Railon Greatjohn is the only (legitimate) son of Karstone Greatjohn and Nancy Whaler, a human male born in the 49th year of King Damian's reign. His mother a merchant's daughter and his father a fairly able adventurer, Railon never lacked for funds, and was given the best education that money can buy. As such, he is fairly nothing like his father, which has lead to some estrangement, especially considering the vast amounts of time which Karstone spends away from home.
Although he remembers none of it due to Janus removing the Dread Lord from history and thereby changing time itself, Railon Greatjohn was once held prisoner under the Castle of Saints in Holy Messia. He was freed by Titan, though where he was during the battle with the Dread Lord is unknown.
