Cuirass of the Savior's Hide

The Cuirass of the Savior's Hide is a piece of armor created by the Daedric Prince Hircine. It gives the wearer a small resistance to magic. In Oblivion, one completes a quest for the Daedra Lord Hircine. One must kill a unicorn, and then take its horn and bring it to Hircine as an offering, to receive the Cuirass. No such prize is required to gain this rare treasure in Morrowind, though an equally challenging, if not more difficult, ordeal must be taken to receive it. It resides in a heavily locked cupboard in the Hall of Fyr in Tel Fyr, and the key sits at the end of an undocumented quest, a long string of keys and locked cupboards which also lead to a Daedric Crescent, a huge plethora of Dwemer artifacts, and another Daedric Artifact.
