That's Associate Chief Fnelthr Plux of the Kalkmaar tribe. He and a faction loyal to him broke away from Chief Onf over the mistreatment of a captured Tusken from another tribe. The whole story was told in a SW short story collection, Tales of the Dune Sea, for everyone who wondered what Tuskens, Jawas, Krayt Dragons, and womp rats really did. Another pearl of modern EU, naturally.

Man, I really wanted to make something like that up last night and post it, but I wasn't feeling very creative. You hit on the the exact same kind of contrived and over explained post I invisioned. Great minds think alike. Excellent post!
