No one knows where exactly Mack came from. Some say he was a famous mob boss who got bored of being in charge, faked his own death, and then used magick to change every aspect of his appearance. Maybe he's a disgraced godwalker, who hid rather than try to reclaim his symbolic throne after getting kicked out of the statosphere. His strange accent and outdated slang might also point to potential time travel. The only thing anyone knows for sure is that he drove into town one day on a Harley, robbed a bank, and then invited everyone for a round of drinks at the bar two blocks down.
