Feranor Steeltoe was a Dwarven dragon hunter, and the leader of a group known as the Dragon Hunters. Feranor asked Arthas to kill the Black Drake Searinox to get his heart shortly before the Third War. He forged an Orb of Fire for Arthas with the heart of the dragon.
Feranor's current status is unknown. In World of Warcraft, players can meet his apprentice Sigrun Ironhew in the Badlands who speaks of his master's legacy of using dragon hearts for fiery enchantments, and how the last time he'd heard of him, Feranor was working at a smithy with a hunting party up in Lordaeron. 
- Feranor may be a reference to Feanor, a famous craftsman and smith created by J. R. R. Tolkien.
- Although Blizzard uses the Mortar Team model to portray him, Feranor is just one person. Given his voicen Feranor is most likely the larger of the two dwarves.
