Yeah, no advantages to keeping it. It also weighs a lot, and at least for me I couldn't ever drop it anywhere because it's a quest item. So I would just sell it to the orc librarian.
Doesn't seem to have much of a purpose after you use it the one time. If it wasn't a quest item and you could drop it, I guess you could use it as an Elder Paperweight.
look at it and reload i dkubt ull go blind, its probs more like a just saying thing and ya id sell it
Actually, if you try to read it outside of that one specific time when you're supposed to, you DO go blind for a few seconds. I thought that was rather neat.
