Raiment of the Crimson Scar is an enchanted Light Armor set found in the plug-in of The Vile Lair. After purchasing all upgrades, including the Ichor of Sithis from Rowley Eardwulf, Greywyn's Armory will appear in the bedroom inside Deepscorn Hollow. It can be found in one of the cupboards beside the coffin. For the history of the Crimson Scars, see Greywyn's Journal.
