The Roaming Hermits

(The Sahara Desert, Border of Egypt)

Four people were roaming the places, and their robes were filled with sand. One of them had a conical hat on their head, while the others followed behind him. 

He was looking at something that was on his hand, and when he reached a certain place, he stopped. He took a seat and was looking around the place. 

"Seems like it", he muttered as he sat down. The other three that were following behind sat down, and one of them began to massage their legs. 

"You never told us why we were here", he asked as he looked at the man under the conical hat. The other three were wearing normal straw hats, as they had to shield themselves from the heat that was around them.

"You will understand at nightfall", he replied. He pulled out a sac in which he had water and sipped on it. He circulated it through his mouth, and wet his lips. After thorough circulation, he swallowed it.
