Where is the Dragon armer?

There's no place to find dragon armor but follow this and you will get it but the only way to do that is 1] wear drederic armor and need to kill almost every one in the dark brother hood or just simply do all there missions until the part when they go to dawnstar sanctuary but make sure you sign up for the stormcloacks and finish there mission after that go to river wood or mortal and kill one of the dogs and one of the messengers will come and talk to you and will ask you to kill the hole entire dark brotherhood or will ask you to kill the emperor. Once you do that head over to whiterun and kill the black smith make sure no one sees you or it wont work but if no one see's you don't loot the body yet just wait for 10 hours then loot the body. You will probably find dragon armor in ether 1] in the inventory 2] in one of the drawers in the house 3]murder the shop keeper inside the house if he's in there and wait another 10 hours and loot the body but theres 50 50 chance okay bey.
