Londes was a knight of the Slane Theocracy that invaded Carne Village. He disguised himself as an imperial knight of the Baharuth Empire to lure out Gazef Stronoff into a trap set by the Sunlight Scripture.
He was described as an ordinary human with blue eyes and fairly young man. Londes was a devoted believer and he always despised foolish people who didn't believe in God.
