Perhaps it should have been, but it was not obvious to me that ... Spoiler the corpse on the throne in the room behind Notus was Boreas. When I met Grannus he was 12 feet tall - the figure on the throne did not seem that big. Some sort of trigger to pop up a message like "The corpse of Boreas is seated on the throne - his crown is on the table" would have been helpful. Just my two cents.
