King Mark of Cornwall

Good day to you all! I am King Mark, the ruler of Cornwall, the son of King Felix and the cousin of King Author. I am the brother of Tristams mother, Elyzabeth.  I killed my nephew Tristam for having an affair with my wife Iseult. I fell in love with  Iseult from a magic potion. I was born in 480 AD and lived in Tintagel, where my father was killed during a raid on Tintagel by the King of Ireland. After my fathers death and killing my brother Baldwin, I took the throne.
