“Sir, why the Chain Warden? Is it because you have seen him personally?”
“Because if everyone else sees me as a torturous captor, why not dress up as one? At least during the Harrowing. After that, they’ll just have to continue to imagine me like that.”
If the Harrowing is just a legend in the rest of Valoran, then the people might even dress up as characters from stories. But Viktor knows that the Chain Warden is far from just a story. He indeed saw him once, but not by his own mistake. Although it was his mistake that caused the Chain Warden to point right at him.
