– Moving to the blood gathering quest, here are some places where you might be able to find the following creatures:
(High Elf/ Wood Elf/ Dark Elf) – If you’ve done the Walking Nightmare quest, you’ll most likely have cleared the Nightcaller’s Temple. Inside that temple there should be a lot of Elves. If not, go back to an area that has a lot of Elves in it (preferably the ones that uses magic). Hob’s Fall Cave, Yngvild, etc.
(Falmer) – Back in Blackreach or Aftland
(Orc) – You will find an orc at every Fort.
Note: Don’t kill any NPCs. Get the blood of the enemies that you slain.
– Once you’ve gathered all of the bloods, go back to Septim. He will then open the contraption in his side that will reveal the tome.
– Take the book from the Pedestal.
– On your way out, you’ll meet Hermaeus once again. Decide whether you want to work for him or not. To this point, it doesn’t matter what you choose.
