* CrazyAwesome: The Arch Zealot of the Redemption. Purges heretics and mutants with chainsword and flamer, has a flamethrower hat, and is considered too extreme by the other Redemptionists. What's ''not'' to like?
** When the plot was first developed in 1990, the idea of mining pollutants and prospecting for technology were nice conceits. Nowadays however, there are places where soil is so polluted you can mine it for cesium, and many people make their living scouring landfills for electronic items richer countries have discarded.
** Years later, the Tau would be introduced to 40K, and the names of the Spyrers' suits all happened to be words in the Tau language that accurately described the suits' abilities.
*** Note that when they were first introduced, the Spyrers' suits were said to use alien technology. Later, Games Workshop just happened to add an alien race to the setting who are technologically advanced and much more open to other races than just about anyone else in the setting. Hmm...
