Is that the one in which Niven introduces us to thrintun and whitefood?
What was the name of that scientifically adept people who developed the whitefood to be resistant to the psychomanipulative abilities of the thrintun?
I'll probably think of it before you reply.
Ugh... tough one.. I think you're referring to the Tnuctipun. At least, the story "There Is A Tide" in Tales of Known Space refers repeatedly to the "Slaver-Tnuctipun War", although I'm still not sure if there's a difference between the thrintun and the Tnuctipun. Far as I can tell, they're the same species.
