Bring Shango's Pelt to Buck Cantwell at the Nesingwary Base Camp.
Shango awaits, [player]. If you have succeeded in your tracking, he will not know that you stalk him, and you will need the advantage.
He is supposed to be bigger, stronger, and more ferocious than the other dreadsabers of the basin. Travel north, to the western shore of Bittertide Lake and near the falls that feed it, do battle with Shango. If you succeed, return with his pelt.
