King Morus ascended to the Golden Throne when his father, King Bellodar III, passed away from natural causes. Unfortunately, Morus descended into madness over the course of two years and grew paranoid about his newly acquired power. He accused his brother Alathos of attempting to seize the crown for his own.
The two brothers fought each other in a wild sword-fight and Alathos was forced to kill his brother. Following the duel, Alathos I ascended as the new king of Impiltur.
