Thank you Survivor Boy, Btvs Vamp, CSCin3D, Zep and hagiz1 . :)
CSCin3D, great stuff! Thank you for the lesson on pronunciation!
hagiz1, I can't find anything online about the word " Uroluk" in relation to Palau.
Zep, my avatar is a Hawaiian petroglyph of a war canoe.
Survivor Boy, maybe the names are as simple as Fans and Favorites. The only argument against using those names would be that eventually the contestants will merge or maybe SEG will mix them up at some point.

Considering the use of the war canoes, the theme this time must be an island warrior theme. (The first S-Palau had a WWII theme). I did a little research this morning and most of names of warriors in ancient stories would be tough for Probst to shout out during a challenge.

The ceremonial war canoes were borrowed from the states of Ngiwal and Ariai, so maybe the tribal names are in honor of those states. That's a guess, not a spoiler, and it is probably wrong.

The cast will be announced in Entertainment Weekly tomorrow. Maybe we'll learn the tribal names, too!
