The Elder Scrolls V: Skyrim - Entering the Reaper's Den (Soul Cairn - Dawnguard DLC)

The Elder Scrolls V: Skyrim's DLC Dawnguard takes you on a rather vampiric story. Traveling from Fort Dawnguard to Volkihar Castle you'll also stumble upon the Soul Cairn, a purplish plane full of horror. The biggest terror of them all is the Reaper. It takes a good snoop to find al the Gen Shards it takes to meet him, but when you do, be sure to fight and not to fear the Reaper. I do not use mods.
