The Knightroad Family:
The knightroad family was formed when the paladin Amnail married the cleric Augusta. This was 598 years ago. And since each generation has seen a Knightroad become a paladin who have accomlished great things.
Great grand parents: They would have two sons and a daughter. Both sons were killed as children.
Grandparents: They would have two children both boys(Dietrich and Virgil)
Parents: They would have one child as Virgil died at a young age. They did have an adopted son as well.
The Knightroads symbol is a blue rose. This is something Amnail thought of as he had seen them(though they do not appear in this realm) and was inspired by their beauty.
