The Point of this Purple Plains Stuff

I actually got so far ahead of myself I forgot to mention: the reason for all this writing inspired by a randomly-generated biome (aside from the obvious occupying the empty hours of my finite span) is that my ultimate plan is to weave three randomly generated biomes together into a modestly-sized but hopefully entertaining hexcrawl.  The other two have already been generated, but I want to come up with a decent mini-gazetteer of the Purple Plains before I get to them.
