No this was apparently wrong. Please don't repost that link again. I made the same mistake.
the correct 'achievement' is

I think the Scrolls of Elun'dris are probably sold by a nightfallen you have to rescue to join the resistance like Absolon. Luniel is probably a bad idea to begin with because she doesnt have a quest, but someone else might.
