9th Dawn III

In order to get this achievement, the first thing you need to do is talk to the dude at the yellow star who will give you the quest. From there, go to the Hole of Kol (east of the dude, blue star on map) and finish it. Near the end you'll find a chest with the camel license. From there return to the dude who will ask for 100,000 gold. Next he will ask a dumbass question, I answered "camel hump" though it probably doesn't matter.

The camel is actually a pretty good mount as it moves super fast. You can even cast spells while on it, though you can't use your weapon's regular attack. Note that it stays where you leave it, and there doesn't appear to be a marker on the map for it so you need to remember where it is. There is a 3 ability coin ability called Call Mount that you can use, so once you have that you don't have to worry much.
