Theo's mask

Theo's mask is a very specific type of mask that is used in theatrical rituels to symbolize Theo.
The real mask is an old relic that seems to be as if it was here at the dawn of time. No one knows where it came from but some people think it had to do with the Myth of Theo, but no one knows for sure. All they know is that it was found buried underground at the entrance of the city Theatrical London.
