The Dark Brotherhood isn’t one of the popular guilds in Skyrim but it does have one of the more interesting quest lines. That is one of the Mod Maiden’s opinion. If you are one who enjoys the assassin guild then you might want to change things up with this mod by JDgenerate. The author does note this is for mature audiences, which makes sense considering these are assassins. The mod overhauls the Dawnstar Sanctuary including adding thirty new NPCS, three new cells and a variety of new conjuration spells and crafting recipes.
