In the north-west, beyond the city and amongst the crags where the worms make their lairs, sands are stained black from oil that seeps through the surface. You were asked to collect a few sacks of the sand and return them to the expedition camp.
'In the habitat where you find the worms, there are sands that bubble with crude smelling oil. The sand is thick and heavy, drawing down most anything too large and heavy to stand upon it.
'There are those in the city proper, however, who prize these sands. For when treated correctly, they can harness the power of fire with it for days at a time.
'I ask that you fill three sacks with the sand and return it to me.'
Make your way to the worm habitat in the north-west crags. Search there for patches of black sand and collect three bags for Abido at the expedition encampment.
You searched the area and found three full bags of tar-sand. Return the filled sacks to Abido at the hunter's expedition in the south-east of the Cape of Umbar.
