A Darkmeyer Slave can occasionally be found in the Hallowed Sepulchre on the first floor trying to open a coffin. Upon interacting with the Darkmeyer Slave he will mention that he needs 100 hallowed marks to buy his freedom from the Mysterious Stranger at the start of the Sepulchre.
If players have 100 hallowed marks on them when talking with the Darkmeyer slave, they will mention that they happen to have 100 hallowed marks that they are willing to give. The player is then given the option to either give the Darkmeyer slave the 100 marks or not to. If the player decides to give the Darkmeyer slave the 100 hallowed marks, he will take them, thank the player for helping him buy his freedom before he departs, and the player will exclaim that "it feels nice to do the right thing". After the Darkmeyer Slave is freed, he will still appear but will tell the player "I think you have me mistaken for someone else".
