After Alister and Zanna introduced themselves, Alister finally discovered that Zanna was the Spirit Queen of Chaos and she was even hailed as the Mother of Chaos.
Was Zanna powerful?
Very.
At least, Alister's battle instincts knew that Zanna was stronger than him. Even he wasn't confident that he could defeat her.
After their introduction, Alister asked her about the situation in the outside world but Zanna was as clueless as he was in that regard.
After all, Zanna had also admitted that she had stayed on the edge of the Mystic Forest for ten thousand years so the information she knew about the outside world was very outdated. When Alister had inquired about her age, Zanna had told him that she had stopped counting at hundred thousand years.
