Two subquests open... 1 is to recover the Stones of Barenziah (currently have 10 of 24)... and 2 is to become a full member of the Thieves Guild. My current gaming temperment is not good for hunting up that last Stone and the question is whether that's tough... If I want to become a full member of the Guild I'm going to have to find all the Stones first?? (I have a list of where they are all located)--I just hate picking things up this way. Same with the irridescent red plants and wooden masks so far--my disposition might change--who knows... I think I'll seek out the treasure map treasures though--I have a lists for these too and the Masks and the Stones--no list for the plants yet. I hope their locations are not random in Blackwater(?)--that would be terrible.

Thanks.

No, you do not need to finish the "No stone unturned" quest to become a member of the thieves guild or the guild master.

You have to become a full member in order to learn what they are. Personally, I dont have the patience to hunt down all of these blasted things. And by the time you find all of them, the reward probably wont be worth it.

I don't actually try to find them. I just happen to run across them when I'm out exploring the world and clearing dungeons. So far, I've found 15 of them.
