Aider and all the ringleaders entered the hall, wearing black cloaks and hoods that covered their identities. They wore black masks to hide their faces, and they weren't the only ones who wore those. Everyone at the hall wore the same costume, making it impossible to recognize each other.
Aider sat on the long bench in the middle row, looking at the people around him, but he couldn't differentiate between men and women. He chose to separate himself from the group, in case the ringleaders were being targeted, he could blend in with the crowds easily and run.
He looked over his shoulder and noticed the people that entered the altar, they came from different directions. He had suspected that the cave might have countless entrances. He wondered if those entrances spread across the Sun City or if the cave was big enough that it connected cities and towns.
