"So be it!"
Rather than one of the sect elders authorised to decide on such thing like the challenges, a grand voice came from the very top of the mountain under which the entire crowd was gathered. If I wasn't wrong with the little information I found about that place, that meant that the council of the ancestors approved for the challenge of supremacy!
As soon as this voice faded out, rather than someone guiding us towards any form of the stage, the mountain itself seemed to erupt from its side in a strange way that didn't produce any debris that would fly all over the place, killing more people in one go than even I would be capable without immersing myself in my upgraded predator's instinct.
"You may now enter the stage!"
