From their announcement:
AB One games has just released some new and updated War Tokens which are free to download from the Father Tilly Yahoo Group. These tokens are an essential element to the Father Tilly (and Grand Ambition and Bloody Kingdom rules) and introduce a number of events or chance elements ideal for adding extra period flavour and excitement to the game. These tokens introduce the possibility of mutiny in the ranks, exploding powder barrels, drunken generals, spies and traitors and a whole of range of other unfortunate and amusing situations. Players should feel free to download these new tokens, try them out in one or two games and then feed back any comments and suggestions back to the group.
