Where can I find the Black Armor/Collector's Edition/April 2013 armor?

I want to find the armor that the guy is wearing in the Dark Souls 2 cover art, specifically the Collector's Edition. It looks really cool and like an endgame armor. I own Dark Souls 2 (and have beaten it) and working on Scholar of the First Sin. Is it in either one of those?

Dark Souls 2: Collector's Edition on Amazon (It'll direct you to the Black Armor Edition, make sure to click on the Collector's Edition.)

Or the armor this guy is wearing in the April 2013 Demo:

I think it is the Faraam Set:

Location:

Starting from the King's Gate bonfire in Drangleic Castle, make a right and head into the great hall filled with petrified spear men. Kill the ones at the top left corner to expose a room containing a Ruin Sentinel. If you walk inside the room with the Ruin Sentinel, a piece of the floor inside the room will collapse under the player, having them fall into a cave including the "Under Castle Drangleic" bonfire. The cave will include a corpse containing the Faraam set.
