Old Neil
Old Neil was a Beyonder of the Hermit Pathway—basically someone who'd achieved a pretty high level of power through that particular mystical tradition. He's best known for mentoring Klein Moretti early on, teaching him the fundamentals of Mysticism while they both worked at the Blackthorn Security Company.
The guy lived by a pretty straightforward philosophy: do what you want, just don't hurt anyone doing it. It's the kind of motto that sounds simple until you actually try to live by it, and fans of the series often note how much that principle shaped Klein's own moral compass in the early days.
