Dune Teardrinker?

I have done all the polymock quests so far, and on wiki it says there is a guy called dune teardrinker who i have to play to get a aloe seed or something, but the problem is, there is not a quest for him at the polymock master, so my question is where can i get his quest and where can i find him?
Ty in advance for your help.

Go here and have a look around:http://gw.gamewikis.org/wiki/Quests_...f_the_North%29

I had that same problem. I killed the necro, came back to the master, took the reward, registered the new piece, went back to Hoff and he would only give me the description of polymock -- no new opponent to fight at all. I went to the "Report a Bug" section here on this forum and described the problem in as much detail as I could: what I had been doing just prior to the problem, what pieces were already registered, etc... and when I signed on Sunday morning the quest was available to me.

Good luck to you, I know it was very frustrating for me, but it was also fixed in less than 24 hours once I reported the problem.
