The battleground is ostensibly a tomb for his dead lover, and he defends her grave with every ounce of his being. This has been corroborated by From Software, which stated that players have a 93-percent failure rate while fighting The Fume Knight.
Why He Is Great: The Fume Knight is the toughest boss in Dark Souls 2 and is considered by many to be the hardest fight in the entire series. He left his service after clashing with a fellow knight and became corrupted. Who He Is: The Fume Knight was a traitor to the king of Drangleic, the world in which Dark Souls 2 takes place.
