Feln hailed from the time of ancient Krypton. Very little is known of him save that he was the earliest recorded progenitor of the El family line. He was born during a time when Kryptonians were known by only a single name. Feln was the father of Rugad, who was the father of Tomnu who was the father of Erok. Erok was the first Kryptonian to adopt a House name and became the first actual member of the legendary House of El.
