Minimum crafting level of 50 is required to obtain this quest.
You do not need to have any prior reputation with Teren's Grasp; however, if you haven't worked with them before, you'll need to manually hail Wyneta, either via keybind or by right-clicking her to select 'hail'.
If your adventure level is below 70 and you cannot get the Sokokar quests, you will need to utilize the spire network, which will take you directly to the center of Teren's Grasp.
If Varick is not viable when you return then you may need to target him by typing /target Varick then hail him. This has happened to me on 3 different computers on every character I did this quest on. You may need to do this on each turn in for the following quests.
