With Judith's shocking display of might, turning the tables at the last second, the orcs were too stunned to fight. They couldn't understand how she had done it.
How she had cut their Chieftain from shoulder to hip. A sight they couldn't accept.
Their shock lasted only a few seconds, but those few seconds cost them dearly. Where the fight before had been 60:40 in favor of the players, it was now a slaughter.
Judith was too tired to join in it, luckily, the orcs didn't attempt to kill her in her weakened state. While their culture respected duels greatly, the 'what comes after' was less clear. It was perfectly acceptable to challenge the winner to a duel after the fact.
This was what made the ruler of even a small camp like theirs such a fearsome foe.
The ruler was the one who had survived such a barbaric war for supremacy. He had needed to display such might that the others didn't even think of challenging him.
