Ledd Mettle is the Eldest son of Icarus Ronald Mettle, who would often shorten his name and go by the moniker of I.Ron Mettle. I.Ron Mettle was the previous Head Forgemaster of the Equestrian Militia, the position that Ledd now fills, in the grand forge of Hephaestus, deep in the underbelly of Canterlot. Unlike his Unicorn Father, Ledd has Taken after his Earth Pony Mother, Glimmering Mettle, And has no horn and limited magic use of any kind. This made it hard to follow his Fathers footsteps, but he Developed many new tools that allow him to do the same work with equal efficiency.
Ledd is about average size for a Stallion, and despite his strength and physical abilities is very lean. His mane is kept very short for manageability at the forges, is a Dark Grey Color, and His Coat is a Lighter Grey. Originally Ledd had blue Eyes, but due partly to an over-exposure to heat from the forges, and an accident with a pot of molten silver, the colors of his eyes have been burned away
