Hi folks,
Thanks all for your help with this. In the end I used Andrea’s suggestion of the Weinberg book to develop some exercises and then finished with werewolf facilitation. This filled a three hour session all together and went smoothly enough for now. I can highly recommend the ‘What did you say book’. It’s short and to the point with plenty of exercises you can use to build up a workshop.
