It is worth noting that any items left in Orson's inventory at the end of Chapter 5x will be lost forever. They can be preserved by trading them to Ephraim, Kyle, or Forde, who will keep all of their items.
Sometime before the storyline, Orson was well-known among the knights for his love and devotion to his wife, Monica. After her death, his behavior greatly changed and he made a deal to betray Renais and side with the Grado Empire in exchange for Monica's resurrection.
He is first seen when he is accompanying Ephraim, Kyle, and Forde during their assault on Renvall Castle. Unbeknownst to them, he is secretly working for Grado. At the start of Chapter 5x, Tirado refers to Orson when he says "along the prince's side is a friend. When the time comes, that friend will come to our aid."
Before the beginning of Chapter 8, he greets Eirika and Seth when they approach Renvall Castle, claiming that Ephraim is imprisoned inside of it. However, Seth quickly becomes suspicious and points out several things that reveal Orson to be a traitor.
Following his betrayal, Orson leaves Renvall Castle and returns to Renais to be with Monica. As time passes, he falls deeper into madness, not realizing that Monica is only a corpse. He appears once again in Chapter 16 as an enemy boss. By this time, he has been placed on the throne of Renais, which he makes no effort to rule, causing it to fall into chaos. It is stated that he never allows anyone to enter the royal chambers and refuses to accept meals. At the start of the chapter, he brings a birthday gift for Monica. However, he soon discovers that Eirika and Ephraim are attacking the castle and thus is forced to fight against them to keep his home. In the end, Orson dies in the fighting and his zombified wife is euthanized.
