Cail received the card out of curiosity. It looked very official with a government mark stamped into it.
If this organization is legal, then the reason why they probably lack staff is 1. There aren't enough Void users, 2. They all kept dying so they gotta replenish it quickly.
The woman seemed to be determined to get a good impression on Cail, she wanted to approach him, but Cail backed away. Sensing that Cail was still wary, the woman did not mind and her determination didn't waver.
She started talking like a tour guide: "We are now inside a void rift." Then she opened her arms and twirled, "And thiiiiis city, is a city eaten by the void." As the wind blew her dress, chimes sounded from the metallic bead-like design on her skirt.
"Weirdo," Cail said to himself. Since this woman was happy to help, then he might as well ask, "How did I appear here? Is there a way out?"
