I interpreted this differently. There is some slight contradiction in the item descriptions surrounding this. Ring of the Sun's Firstborn: Lord Gwyn's firstborn was a god of war, but his foolishness led to a loss of the annals, and rescinding of his deific status. and Sunlight Medal: lost his deity status and was expunged from the annals. I think that he did something foolish, which is undisclosed, and this led to him being expunged from the annals, which means "a record of events arranged chronologically by year". So after his foolishness: he was banished, all of the statues were removed, and he was literally erased from history so that not even his name is known.
