Wow PsychoPere, thank you very much. I had actually read the Thrawn trilogy but quite some years ago so have forgotten the Chiss. I remember the Mirialan now from AOTC (and I think I have a Luminara action figure somewhere..).
As I recall my intention was to play a Smuggler and I see they come in human, Twi'lek and Mirialan form so I may well go with the latter. I'm sure there will be Twi'leks aplenty, LOL>
