Uh … sure. Arguably, you have us covered already by covering the Way of the Winds, which recognizes us as practicing the same faith by a different name.
I don’t think it’s quite the same, though.
“Achura,” whether as a nation or religion, typically refers to the rural population of our home planet, which we call by that same name. (The cities are culturally, and religiously, Caldari.) Our beliefs are pretty diverse, ranging from animism to a sort of monist spiritual skepticism, but we still see ourselves as a single people and single faith, sometimes called the “thousand sects,” which actually is probably an underestimate. We’re lead by a council of monks from various sects called the Elder Visionaries.
I’ve spoken a little bit about our culture and beliefs here.
If you’re worried about contention, sir, a collection of believers like this might be troublesome. Even ordinarily very peaceful believers can become upset over religious differences-- and what you’re arranging is going to be full of religious differences. Achur monks bicker over doctrine all the time, and we’re all part of the same faith. Imagine what it’ll be like with so many.
Also, aside from Miz’s remarks, Amarr is probably the single largest and widest-spread faith in the cluster. If you’re going to try to represent the various faiths, you’re kind of going to be making a large and actually rather provoking statement if you leave them out. Ironically, you’d be lending support to the Empire’s most militant elements by implying that the Imperial Rite can’t be treated like a civilized religion.
