Head for the big door in the North-West of Undercity, the one with Guard Weyr outside of it. Once inside, you'll need to head to the upper floor (behind the Buddah shrine). And they don't "take" your Aurulite, you use it like the seals in DF.
Edit: Ran in and whipped this up. I'm thinking that it should be the same for Alb and Hib vendors. Anyone want to confirm? Al'' try to get specific info added later.
