He is considered one of the evil elves, with the Iorwerth family having taken over Prifddinas years ago. It is believed that Lord Iorwerth broke one of the nine seals of the Grand Library, made by Seren the elven goddess. The nine seals were used to protect the vast knowledge kept there from reaching the hands of humans. The library is located underneath the elven city of Prifddinas, which is currently inaccessible. However, the reason for his actions is unknown. He gives a Crystal pendant to you during Regicide so you can prove you are working for him.
