3rd edition Tau, when they were still positive, optimistic and weren't being painted as brainwashing space-communists. At least their society wasn't depicted as being an absolute nightmare, unlike everyone else.
This, but probably I would go with the Adeptus Mechanicus.
Beeing mostly away from the front lines, worshipping (maybe) the most powerful C'tan, who is sleeping on Mars and beeing allowed heretical veiws just because those Imperial dudes can't keep their tanks in working order themself.
An by the way I play Necron in TT so a Necron Lord (that gets to keep a lot of their personality compared to the robotic space-zombies that is the common Warriors.
So:
1-A Techpriest of the Adeptus Mechanicus
2-A member of the Tau air caste.
3-A Necron Lord.
