-    description= _ "Explorers are often utilized as heavy scouts, no longer just probing the enemy but conducting raids on the supply lines or eliminating patrols. Often away from the main body of the army for long periods of time, Explorers have no issue pilfering these supplies, and so they tend to be more well-equipped than most."
+    description= _ "A slow-moving caravan out in the open desert is a prime target for bandits or marauders. In order to protect themselves, the Dunefolk employ Explorers to scout and repel potential threats. In doing so, these fleet fighters not only protect their vulnerable caravans, but pilfer the supplies of their supposed raiders for themselves. When employed for warfare, Explorer no longer act only as scouts for probing enemies, but are skilled enough to be effective flankers or potent shock attackers."
