Morphic Street Conspiracy
The Morphic Street Conspiracy was an early form of rebellion against the tyrannical Lord Winder. In the original timeline, their meeting was raided by the Particulars under Findthee Swing. After Commander Vimes/John Keel altered the timeline, the revolutionaries were able to escape the raid. They then started a mob and met Keel and the young Sam Vimes back at the Night Watch station on Treacle Mine Road. The revolutionaries had apparently been communicating through secret messages hidden in Cut-Me-Own-Throat Dibbler's meat pies. The password to get in was 'swordfish'.
