Clovis panted heavily. He definitely recognized the last voice. It was Mara. Mara had indeed joined the Libation Fiesta. So, he couldn't help but wonder if his wanting to make Mara join the Libation Fiesta actually came from the real world.
He realized he had found a clue all this time. Back when she encountered Christina, a system actually made her more interested in Christina.
He thought that Christina might allow him to find a clue about the system. The Elseingarde family had tremendously helped him, but he realized that Christina had never brought him a clue.
The only time the system ever appeared because of Christina was when they first met.
So, it might actually be influenced by his desire in the real world or the system had been designed in a way that Clovis would be able to gather all his people.
It didn't necessarily require them to be a part of the Libation Fiesta, such as Vina or Hana. But their relationship would be quite close.
