The battle quickly devolved into a flurry of blade techniques, with each pair well spread out so that they didn't have to risk "accidental" attacks from their allies or getting pulled into a larger four-person fight.
Their actual skills were mediocre at best, and everyone could see that the Elders from both sides were visibly embarrassed by the display, even through the open hostility that they were showing each other.
The match ended with two combatants from the same side remaining, and it was clear that they would much rather keep fighting with each other than accept the victory as a team, but the referee was not having any of that, already annoyed by their lack of professionalism.
"Enough. The Shard Rune Sect wins the fight. You can kill each other on your own time. Now get out of my ring." The announcer declared, bringing laughter to the stadium.
