This is one insanely awesome custom-made “First Age” Sauron leather armor inspired by The Lord of the Rings. It was created by Samuel Lee from Prince Armory and the craftsmanship is brilliant.
Creator explains:
Instead of the typical medieval fantasy spinoff (its already that anyway), this design is more focused on a scenario of what might Sauron’s armor looked like in the first age (Far before the well known 3rd age featured in the Lord of the Rings films). I won’t get into the volume of lore left behind by Tolkien but one thing worth noting is that Sauron himself was a capable artisan and armor smith. Perhaps he would feel at home in this armor.
