So Far I have collected Volume 1,3, and 4.
I'm missing the second one if someone can show me where.
In return of these books I gave it to Urag gro-Shub in the College of Winterhold where he gave me 1000 gold for each book and the translated editions.

So how many volumes are there to collect? This expansion so far has been about collecting, collect these 10 pages, collect these 3 reaper fragments, now volumes, sigh... kinda don't like it , especially because I'm such a completionist. .

Four. Don't forget about all the paragons as well.

How many paragons are there then? I got the Amenthyst Paragon, Emerald Paragon, and the Sapphire Paragon.

I think 5.

I assume it's Ruby and Diamond right...

Yes.

Can you only go to the forgotten vale only once??

Might you know where they are located and the 2nd volume? Like what part in the map?

Second volume is located through one of the paragons portals. I believe emerald. Unfortunately, you'd be better off looking for the locations somewhere else on the forum as I haven't memorized their locations.

As many times as you desire. You can fast travel there, and easily navigate it through the Wayshrines.

Good to know...on a side note can you turn other npc into vampires aside from the quest an what are the benefits from doing so??

Found the Ruby Paragon on a Frost Troll in the inner santum by placing the Ewer.

Where did you place the ewer in the inner sanctum?

Anyone know where volume 4 is?

Volume 4 is in a falmer hut in the section that is sort of like a big village that is shortly before the Wayshrine of Radiance.

The Ruby Paragon is the most important since it will get you to Auriel's Shield which is quite a fun toy to play with as long as you have the power bash perk. (Of course, it is sorta redundant since Fus Roh Da does the same thing.)
