richard (tales)
The prince of Windol Country in Tales of Graces. He once was peace-loving and somewhat trusting of others. When his uncle tries to kill him to seize the throne, Richard begins to distrust others to the point of hating everyone. He even launches an attack on Lhant, even though he is Asbel's friend.
This is all due to Lambda's negative influence possessing and warping Richard's mind.
