Arthur can give him a certain amount of money, as well as offer to help several people who were previously kidnapped. You need to start searching from the market, next to it is a building that belongs to a local fencer. There is a bookshelf in a small side room. The marks on the ground will tell Arthur that it has recently been moved.
Morgan will have to question the swordsman. This can be done without bloodshed. He will tell him that one of the books is a switch, it opens a secret door. Behind it is a descent to the basement, where the kidnapped people are kept. Arthur will only have to release each of them.
When Morgan takes out the prisoners, no one will stop him. After that, he would have to meet monk Dorkins, who would offer him money. Arthur can either accept them or refuse them.
