Rain after completely awakening the Aldore blood within him, something only a person hailing from the Aldore lineage can do. Since this requires the continuous use of a person's magical energy in order to surpass his or her current limit of power, it puts his or her life in danger. Aware of the risk, Raegen kept this type of awakening a secret from Rain to ensure his safety.
The Aldore blood running through Rain's veins had been dormant for a long time, until it awakened after touching the earth crystal during his childhood. At the beginning only his right arm had awakened, but he eventually managed to completely awaken his powers during a duel against Lasswell. Now he can control this ability at will, and is able to fully awaken his powers whenever he wishes.
Rain after completely awakening the Aldore blood within him. Legend has it that only someone of the Hess lineage who has fully awakened his or her own powers can take on the overwhelming power of a full Aldore awakening. However, according to historical accounts, no such battle between two fully awakened warriors has ever taken place. Even in the duel between Raegen and Rowen that occurred during the war for the independence of Hess neither of them fought while fully awakened.
