“ One of the camels in the caravan trips over a dark rock protruding from the sandy dunes. The poor animal has broken its leg and cannot continue. A cacaphony ensues as the animal suffers and the caravan train overseers complain passionately as they redistribute the animal's load across the caravan. (Let's just hope none of the PC's was riding this camel, shall we?)
As the camel is put out of its misery and the camel is skewered over a campfire - waste nothing! - someone takes a minute to inspect the root cause of all the trouble. To their surprise, the upturned rock is worked stone. Some frantic digging may excavate the bottom half of a gorgeously worked1 obelisk, and maybe even the small square forum below; but a more rigorous exploration of the surrounding dunes reveals a buried tomb doorway on each side of the forum.”

“ By late afternoon, the sky starts to cloud over. The sun shines behind the fluffy clouds, gilding the edges and showing a Jacob's-ladder of rays streaming through the gaps...very pretty. Gradually the clouds shift into a new configuration: you realize with awe-struck, preternatural clarity that the clouds form a map of a coast-line that you know, against the blue sky as ocean: surely it's a Sign! Suddenly, the golden beams coalesce into one long ray that strikes across the blue. A star-like gleam flashes under the ray: perhaps it is an island? But the charts show no island there...who would want to hide an island? Who could do it?”
