Story spoilers
Laplace betrayed Ruijerd's group by giving its warriors devil spears that drove them into a violent state in which they killed even members of their own families. Ruijerd fatally wounded his son, who managed to destroy the spear and free him from its influence. Ruijerd considered suicide afterward, while the surviving warriors swore revenge on Laplace.
Years later, Ruijerd intervened in the battle between Laplace and three heroes and finally achieved that revenge, though defeating Laplace could not undo the damage already done. He then took on the goal of removing the infamy attached to the Superd race.
