Yeah I can't seem to think of an appropriate clan name. I looked at some of the old stuff written about fubarnii language on the wiki pages, but there wasn't much about moons really. It did however say that one of them was called Enar, the larger one I believe. Seeing as their gods are called enarii though I thought it might be a little presumptuous to name a clan in that direction. After all they are essentially a merc clan, didn't seem to fit the image of sacred. Although if there is a name for the smaller moon it could be nice to tie in to the city name, but I still however would think that a generic word for moon to use for something like tower/city of the two moons or great city of the moon would be better.
One possible idea is that I could tie in some Japanese or use it for inspiration, lunar eclipse is Gesshoku (quite funny because it essentially means eaten by the moon) for example and moon itself is Tsuki or Getsu/Gatsu.
The bodyguard idea is fun. I could see them being useful for traders to hire during escort scenarios.
Yeah thats pretty much what I was envisioning for them background wise, I've actually started to a write story to base my force around that I'm going to put up in another thread later. It should feature these guys.
Also any ideas on an area? are the Casani territories special for some reason, a different culture maybe?
