Before Corruption: Belorean was a great and compassionate individual who genuinely loved helping others. His calm and patient nature meant he rarely got angry, making him a pillar of support for those around him. His deep love for Quel'Thalas guided his actions, as did his strong sense of family. Thoughtful and deliberate, Belorean always considered the consequences of his actions before making decisions. He was also a skilled communicator, able to talk his way into convincing others with ease.

After Corruption: Once corrupted, Belorean's personality underwent a drastic transformation. His once calm demeanor turned into erratic behavior, driven by a deep-seated anger toward the world. His love for Quel'Thalas twisted into a burning desire to see the kingdom destroyed at any cost. He became increasingly isolated, speaking little and lashing out violently at anyone who dared to defy him. The compassionate leader he once was became a distant memory, replaced by a man consumed by rage and vengeance.
