Unfinished Tales
The Second Age was dominated by Númenor. The Númenórean helmet, the karma, reached particularly elaborate forms. Those of the Uinendili, a guild of mariners, were "made of overlapping plates of metal, the 'fish-crest' of leather embossed and coloured". Tolkien's coloured drawing of the "karma" of a Uinendili captain features on the cover of "Unfinished Tales".
