Think people are taking everything 'as it is' a bit too much with this one.
Just because there's a Wicker Man doesn't necessarily mean thats the theme, it could just be an element of it. The theme could be based around a mysterious and fictional
voodoo that could work in both Katanga and Mutiny acting as a form of transitional area.
Whilst we know the basic gist of everything in this project such as the layout, some theming items and theme hints (more than any other SW ever) we don't know exactly how it'll all be incorporated into the main thing we don't know - the exact story and theme!
