Raythor was a loyal knight in Phobos's army during Phobos's reign on Meridian. Valuing honor and loyalty above all else, he pledged an oath to serve Prince Phobos until the day he died, and will go to great lengths to fulfill this oath no matter the cost. When Phobos was overthrown by the Guardians and Elyon, he was recruited by Nerissa to join the Knights of Vengeance, a group he saw as a valuable asset to him in his desire for revenge on the Guardians and all the former soldiers who broke their vow of loyalty to Phobos and sided with the rebels during the rebellion. He quickly became the leader of the Knights of Vengeance and led them through many attacks on both the Guardians and Queen Elyon herself.
