A few months ago I was looking at a stageplay of EF (with North as a sort of explorer, Indiana Jones type and his assistant who gets hypnotized!)
But... I don't know the name of the play anymore... looked very fun indeed... who knows the name for me? If you know you get a big hug! ;D
OK, I know the name now (Jordan Blake and the temple of the four winds) but I can't find the video anymore...
