The weightiest armor is skinned creature pelts, tanned and pounded into extremely rough hides, then strengthened with boiled resin and, occasionally, hag magic.
Caught along the western edge of Whiterun Hold by our Nord friend Skegglund Stormcloak, this caged blight on the provinces of Skyrim and Wrothgar is an unwashed mongrel brute and known bedfellow of hagravens. Praying to Daedra and Witchmen, scarred by infected tattoo and ritual markings, Cagarach was ready and willing to accept a knot of poisoned briars for a heart, in order to master invincibility in battle. Yet here he sits, spitting at us and wallowing in his filth. The smell from the armor would make a troll's eyes water. But the clan makings and primitive stitching require further inspection.
Aside from the feet, which Reachmen sometimes leave exposed to aid in their movement across scree and down ravine, even the weightiest armor is skinned creature pelts, tanned and pounded into extremely rough hides, then strengthened with boiled resin and, occasionally, hag magic. Bones are sharpened to ensure even a glance from a shoulder plate or fan plate results in a deep slash to the victim, the most hapless of which are pierced to the skull. Helms are twisted bone or pointed antlers. Weaponry is bear, wolf, or found carrion bone, or sharp-edged flint for an axe, woven with leather strips, spittle, and other, less savory, bindings. Black briar thorn arrowheads with raven-feather tails fly from their bows, drawn on strings made of the guts of the recently slain. A mocking grave singer, soon to be put to the sharp end of my sword.
