The Four Rogues is a group consisting of, predictably, four human rogues. Its members are:
Andrew Korban
Elijah "The Brave"
Jack O'Lantern
Jack O'Hearts
There is, it would seem, a high probability of them eventually meeting a third Jack, last name O'Alltrades. There is also a more mythical "Jack O'Whatever."
Their Story so Far
These losers solved every puzzle I threw at them effortlessly, got to the door of the boss of Violl's Garden, and then heard it scream and decided they were "not drunk enough to deal with it" and literally walked all the way back to a fucking tavern.
