"Centaurs"
"The last thing— the sound of the many horses and their hooves— that's the Centaurs! A creature with a male human upper body and a horse lower body."
It was greatly known as the shape of Sagittarius in the popular zodiac among humans.
It was good at archery and could be comparable to the elves.
"When there were centaurs around, the Gate of The Underworld was also nearby!"
These three things had already proved that the gate in front of them was a real Underworld's Gate, so the question is...
Who summoned the gate? It was said that only the king of the underworld could, or the guardian of the underworld.
Could it be...there was Cerberus here?
That three-headed hound was the underworld king's beloved pet and the crowned guardian of the underworld.
Just when the elder was thinking about the Cerberus, the three creatures that the elder mentioned before slowly appeared around the gate one by one.
