I think the original idea was mine, with Cador (who wrote the code) and I think Twist contributing ideas as we hashed it out.

My idea at the time being that most cabals had some kind of power which in some sense either forced you to play by their rules or set some kind of consequence for not doing so, e.g., Battle's spellbane made casting spells on them, something you'd normally want to do as a mage, not such a great idea, Tribunal's wanted let them assign consequences for breaking the law, and so on. Knights didn't really have that, and it seemed interesting to give them some kind of capacity to force an enemy to fight them with numerical parity if not honor in a broader sense.
