In the Kingdom of Försyn, Alexander was to meet a tragic end for a curse his parents passed on to him. Alexander fell from great prestige to absolutely nothing by trying to bring justice to the people that were killed by his parents. He was told to end someones life that was dearly close to him by a prophet after he was informed about the curse. Alexander soon learns that his flaw caused him to do this, and lead to his demise.
You must kill your father.
In the Kingdom of Försyn, young Alexander was born to the Queen and King. He showed great power even as a child, proving that he was worthy of nobility. What he did not know, is that many years ago his bloodline was cursed by the gods when his mother and father committed a grave sin of gluttony, as when a time of famine hit they let their citizens starve while they had the entire food supply for themselves. The curse made him bound to die an extremely painful death.
Stop you fool!
When Alexander grew into a man, he was liked by the entire kingdom. Everyone greeted him nicely, and often gave him their thanks for saving them. To the kingdom, Alexander was their savior for being so strong and kind to everyone.
One day when Alexander was traveling, he met a prophet who told him about the curse he had, and how he must kill his father to cleanse himself of the curse. Alexander agreed only because he heard that his father decided to let the village people starve.
The day after the prophecy was foretold, Alexander rushed to the castle to kill his father. His father was screaming in pain as Alexander lunged the sword through his heart, killing him in seconds. The guards immediately heard the scream and jailed Alexander for the crime he had committed.
In his jail cell, Alexander acknowledged his fatal flaw, his instant decision making. Once he has made his mind up he can't change his mind until after whatever he decided on has been fulfilled. He made the realization that he killed his own father, and how what he has done can never be reversed.
The day after, in the town square Alexander was hung for being responsible for the death of the king. In his last moments, Alexander thought back to his curse, and realized he only fulfilled his destiny.
