Thanks all, we enjoyed playing through the campaign and it was fun putting the different tables together.
The mat is a forest mat from PWorks. And yes I also play a fair bit of Conan and have ideas for a future show participation game.
In the lockdown we can't get to play, so I'm adding to my Congo figures to build up a MWWBKs field force for a future campaign based on an article in WI a few years back.
