The three still breathing bodies are disarmed, and comforted. The next day, about noon, one of the injured people awakens, after coversing with Sul'Dan for a short while, he goes back to sleep. By nightfall, all three of the people are awake. After some generous healing from Arcanra, they are back up to full health. They make the party wait one more day, and then begin backtracking towards their village. The next day, they arrive at their village. There, they get some food, and reprovision the party, (with food for 2 weeks). Then, the previously armed man (I'm assuming you returned his mithril shirt and weapons) agrees to guide you towards one of the Shade's operations. After three days of him leading you through the desert and traveling at night, you walk over the rise of a dune, and see an Oasis with a couple of trails of smoke coming out of it. It appears that the sight where you meant to camp the night is currently occupied by a caravan.
