Nobody is safe on the Txepiva plains.
The Txepiva live in small clans permanently on the move. Unlike forest or reef folk, they build no long lasting homes. In the deeper plains, where volcanism renders life a lot more difficult, fights for the right to inhabit an oasis will easily escalate to deadly violence.
Txepiva warriors weave bone or even metal around their tswin, as decapitation at the base of it means certain death (as depicted above).
While the Omatikaya are great hunters, they are not nearly as used to warfare against other Na'vi as the Txepiva are.
You can see the differences between them too: Ran'seo (the Txepiva) has a hairless tail, notched as a status symbol. His ears are much larger, and also notched to mark his bonding with Tsealim (stunbats). His nose and eyes are also larger, adaptations to life in low light and poor air environments.
