Finished this while waiting for Simcity to download, but of course Origin refuses to give me my product 2 hours after midnight... THANKS, OBAMA.
Anyway, these guys are sort of like sand ninjas that have been training in the harshest environment in the known universe, making them the most deadly warriors on Arrakis. In the first three books, these guys wreck everything. Their Krys knives can't be sheathed once drawn unless they are coated with blood, and they don't leave their dead behind in order to preserve the water of their bodies. unadulterated bad-asses.
I figured that they would need protective sleeves for their arms and legs more than regular stillsuits- not for fight protection, but just from regular climbing and stumbling over rocks and sand and riding sandworms in their spare time since Fedaykin are so active. They wear inscribed clothing since they are raised in a very religious culture (much like muslim and christian warriors used to) as protection or blessing, and the round water counter-like jewelry. Fremen gotta 'frem yo.
