Alpacas are beasts found in Vol'dun on Zandalar. They are commonly domesticated by the vulpera and Zandalari troll exiles in Vol'dun. At least some vulpera use them to pull caravan wagons through the desert. The Zandalari exiles at the Scorched Sands Outpost rely on many things provided by the alpacas for survival, including their meat, fat, hides (used to keep warm during cold desert nights), and milk (which can also be made into butter or ricotta cheese).
Some alpacas are also found accompanying humans and grummles.
