The Keepers are actually easier to get into than the Wilde or Aoi Iseijin (kusari wilde) but if you try hard enough, anything is possible!
Anyway, welcome to discovery. I suggest you set up first either a researcher if you are interested in Nomads/wild. Other than that, if you are looking for a great place to be/RP, Kusari is a little low on numbers, however, if you go there at the right time, it can be by far the best experience you could have on disco. The RP is hard and complex, but in my opinion, also the best.
I have taken interest into the Xenos as lately as the nomad RP level was a bit over the top for me at my current knowledge of RP. I've already sent an application and i am awaiting the results:)
Thanks for all tips and such! Hope to see you in space!
