circle of the black thorn

I wonder if Black Thorn League inspired the fictional Circle of the Black Thorn which appeared in the last season of Angel:

SPIKE
Who they?

LINDSEY
The Circle of the Black Thorn.

LORNE
Sounds like a little sewing club for pirates.

LINDSEY
It's a secret society.

GUNN
Never heard of them.

LINDSEY
That's 'cause they're secret.
(Gunn smirks)

SPIKE
There's plenty of these cabals about. They usually spend a lot of time in basements paddling one another's bums to prove their manhood.

LINDSEY
These are not frat boys, Spike. The circle's small. It's elite. They got connections you boys can't even comprehend.

WESLEY
They're evil.

LINDSEY
Sure. But evil's not the point. Power is.

WESLEY
Power.

GUNN
OK, we get it. They're bad ass. What do they do?

LINDSEY
(snickers)
Jeez. Are you guys always this slow? Huh? Starts with an "a," ends in "pocalypse." It's a well-oiled machine, this circle. These people grease the wheels, keep the parts in place. Make sure man's inhumanity to man keeps rolling along.

WESLEY
We thought the senior partners were responsible for the apocalypse.

LINDSEY
The senior partners are on a different plane. Down here...it's the players in the circle that make things happen. Hell, you get tapped by one of them, it's kind of like getting the keys to the chocolate factory.

Hakim Bey with his Temporary Autonomous Zones, Imam-of-one's-own-being concept and his Nambla involvement may not seem hellishly apocalyptically evil, but is arguably in the same ballpark as the evil secret society which appeared on Angel.
