Dead Hills is the complete opposite direction tho. The world map doesn't really make sense Oggok wise, since the guard fort is at north end of the valley in that, while ingame it's south. If we go by the world map, the cave would lead to Rujarkian Hills.
Maybe both Oasis and Oggok were supposed to have entrances there.
