 Reaching a mountain range called Suliman Berg, they climb a peak (one of "Sheba's Breasts") and enter a cave where they find the frozen corpse of José Silvestre (also spelt Silvestra), the 16th-century Portuguese explorer who drew the map in his own blood.That night, a second servant dies from the cold, so they leave his body next to Silvestra's, to "give him a companion".They cross the mountains into a raised valley, lush and green, known as Kukuanaland.
