"The march of Hassan had as its object not Red Rock, northwest of Klima, but Four Palms, a Kavar outpost known to him, which lay far to the south of Red Rock. Unfortunately Four Palms was farther from Klima than Red Rock. On the other hand, his decision seemed to me a sound one. Red Rock was a Tashid oasis under the hegemony of the Aretai, enemies of the Kavars. Furthermore, between Klima and Red Rock lay the regions patrolled by the men of Abdul, the Salt Ubar, who had been known to me as Ibn Saran."
