I agree with Ellri on the count of there needing to be... more. You're a good writer Sep, you can manage more detail than that.

Not sure about the gray thing Ellri, most of our Jedi are quite Lightsided already, Xid, Viera and Strago being exemplars of Light and the others only looking gray mostly because we've made them that way with torture.

I do have to say the reason for being there in particular is lacking. Until the sacking of Coruscant the Jedi were embroiled in open war, a war which, incidentally, they were losing. Unless you started acting like a Sith or went totally rogue, the results you got on the battlefield would be what were considered, not your apparent gray nature. Research into the old ways is hardly a point to alarm the Jedi at this point as they, like the Republic, were searching for every edge they could get over the Sith.

Also, I agree with Ellri on the idea of why exactly you would be kept alive. While it is nice to see some more exotic aliens, the Sith empire is (like it or not) quite racist right now. They'd leave a heavily injured Besalisk to die unless he really impressed someone important first, like Nyiss or Jewel, who both took direct part in the sacking and capture of Jedi. That right there is a possible connection, maybe one of those two captured you personally.
