The Forewarning: Tharandar was able to see beyond the veil of time by using powerful divination magic. He would cast powerful spells to scry into the past and the future, gaining valuable insights and knowledge. This allowed him to understand the significance of past and future events, and how they were connected. He is no longer able to do this as the magical cataclysm had a devastating effect on the ley lines and disrupted the magic, making it difficult to use powerful divination magic.
The great war: Tharandar fought in a great war against an evil entity from another plane. The war took a heavy toll on Tharandar and the people he loved, and the experience made him more aware of the fragility of life and the importance of protecting it. The war changed Tharandar's outlook, and he became more compassionate, understanding and selfless.
The loss of a loved one: One of Tharandar's loved ones died during the war, and the loss deeply affected him. The loss of this loved one made Tharandar realize the importance of life and the need to protect it. It also made him more aware of the power of love and the importance of family. This event has influenced Tharandar's outlook, making him more protective and more conscious of the value of life, love and family.
