Zolass in Shamazaar is near the Riss counters, he will give you a quest to get him one of the beasts of burden from the village. Head there and talk to the twonha herder and he will eventually give you a Gui, take it out of your inventory and the twonha you need is in the centre of the village. You will have to simply walk all the way back to Zolass, while trying to keep the twonha from getting stuck walking up stairs.
