Sir Radzig has instructed you to return to Sasau in order to find out more about the bandit recruiters who operate there. There are three primary locals who might know something; the Bailiff, the innkeeper at the Tavern on the Green and the innkeeper at the Wagoner's Inn.
Speaking with the local knacker will reveal a number of odd things that have been sighted in Sasau lately. He mentions that there is a man with a broken leg in the monastery who might know more, but you will have to heal him before he can talk. To speak with Miller Simon you will need to have earned the respect of Miller Peshek and Miller Woyzeck. Alternatively you can speak with the tanner who has been having some trouble with local brawlers.
Go to the crimps' meeting place in the church north east from the tanner.
Before you attempt to enter the monastery, you should speak to Sir Radzig about what the bandits have asked you to do.
