FFXII - Walkthrough - Nam-Yensa Sandsea
Augur Hill: Go west. Go up the bridge. around where the two Bagolys are, there's a bridge... go up the bridge... and there's an Urn! Your map for the Nam-Yensa Sandsea is complete, and you see where you need to end up (that arrow faaaar to the West... hop to it!) No need for directions from me, you can plot your own path now that your map is complete.
Watch out for the area exit leading southeast... those are the Zertinan Caverns, an optional area. You'll want to avoid that place at this time/these levels, however.
Optional quest: go to The Sandscale Bank. Talk to the Moogle. Now return to Withering Shores; follow the running Urutan-Yensa, as they confront the Urutan Eater! Defeat it; return to the moogle. Go east, back to Ogir-Yensa Sandsea, and try to climb the oil platform; you'll see a cutscene. Return to the moogle, for another cutscene, and your prize... some berries.
