Mirage

In the scorching heat of the great desert many lost souls have seen buildings, oasis and caravans in the distance - only for them to disappear without a trace. Many debate if this is some kind of malicious sorcery, a cruel trick of nature or the spirit of this hostile landscape mocking wanderers. By scholars this phenomen is called a "sky mirror" or "Mirage" - and only the most skilled trackers can tell illusion from reality.
