So a small group of pirate/cultist or whatever people is supposed to eradicate all of the people that come into the Sigmas while remaining on a hidden Star City in the same system the GMG has Niigata in?
First of all, our Star City is not in Sigma-59. Second. Yes, we eradicate anyone who refuses to leave Sigmas (less Sigma-13 because the system has no use)
You claim to be in S-21, correct? If you truly want to pull off staying hidden as much as possible from any factions roaming in the Sigmas. I would suggest you to move the whole thing to the cloud Yarasu, the Samura base in S-59, is located in too. It is a worse version of the Badlands and barely explored at all, only the Omicron Sigma connection is known to the GMG and to GC. As well as the planet.
I do not have a problem with a sudden very small opposition trying to get the Sigmas "into their hands", that could get interesting especially since there are a hell lot of groups claiming parts of the Sigmas as their own. Sooner or later the Cult would have to side with some of them. The eradicating everything in Sigmas claiming the space is a bit hilarious but this Cult isn't powerful and we all know that's just an amusing RP goal (:
Amusing as it sounds. Sigma-59 is not a really good place for a Star City. Especially the nebula. Sigma-21 is also barely explored, and has more potential than the already visited, often Visited, Sigma-59.
