Tevurin requested that you recover two types of hides from the saltwater crocodiles on the shores of the Cape of Umbar, the soft underbelly skin and the coarse hide of the back.
'It must come as no surprise that the thick hide of the crocodile that protects the top side of their bodies can also be used as a fine defence for our warriors. What is not as obvious is the value of the soft underbelly.
'Many of the more affluent members of the city desire bags, or water-skins made of that skin; and so, I will ask that you go to the shore in search of complete skins of each type. Six of each, to be precise.'
Tevurin directed you to the shore south and east of the expedition camp in search of crocodile skins. He needs the soft underbelly skins and the tough hides from the backs of the crocodiles there.
You collected the soft underbelly and tougher hides of crocodiles. Take the hides and return to Tevurin at the hunter's expedition in the southeast of the Cape of Umbar.
