This is the Skyrim version for the very popular Underworld armor from Oblivion game, released by zertual.
No bodyslide, this is the minimum weight. Craftable under ebony, up-gradable and with two torso variants, default (same as original author) or dark leggings and armbands.
Edit: Better showcase of the armor here! (Thanks Xuniana)
