It's a clash of two rival tribes, the Chelladins and the Harthans, that was started long ago by their ancestors. The remnants of the Chelladins seeking revenge against the Harthans. We are the Chelladins, the true ancestry of the Chella's long before the migrations of the Titans to the north. "You did a mistake, not once not twice, which will be unforgivable to your generations till you face the wrath of it's remnants, the Chelladins. Their blood is still crying out to you for revenge and you have to pay for each drop of nobel blood you shed, for the innocent children, pregnant women, the old men and the whole village. Blood for blood."
