Desert spice, used in many dishes enjoyed by the people of Umbar, requires collecting and sifting sand where desert fauna deposit spice. Khânai asked that you obtain spice for her.
'Chefs in Umbar say that the blend of spices used to enhance the flavour of their dishes is more important than the collection of any other ingredient. The spice blend is rare and found only in the desert. Worse still is the method for collecting the spice.
'To obtain desert spice, you must eliminate the carrier. Strange winds streaking across the desert or sandworms are known to be spice carriers. Seek them out in the desert land to the north and return to me when you've gathered twelve sacks full.'
Seek spice from the grims and sandworms in the desert north of the expedition camp. Collect twelve sacks of desert spice and return them to Khânai.
Having recovered the spice that Khânai requested, it is time to return the sacks of freshly gathered herbs to her at the Hunter's encampment.
