-    description= _ "Scorchers who have shut out the world for their experiments are given the title of Firetrooper, as both a sign of respect and of fear. No longer cognizant of the value of life, Firetroopers are caught up in the power of their caged fire and likely to test their latest naphtha jar at the first opportunity."
+    description= _ "By refining Sanbaar sap through a very specific distillation process, it becomes possible to produce even more flammable naphtha which burns even more violently than the sap it was derived from. Such a substance is, of course, extremely dangerous due to its highly combustible nature. Even Scorchers will shy away from its use since the potential for self injury is very high, but a few daring souls choose to use pure naphtha as their weapon of choice. The resulting destruction is more than enough to justify the use of such a hazardous chemical."
