The Warlock made a deal on purpose. They did not stumble into the Covenant. They came prepared. They knew what they wanted, knew what they were willing to give, and believed they could bargain with something older than mercy. The worst part is that it worked. They got more than others did. More power. More access. More permission. But the cost was higher too, and the bill is still open. The Warlock is not fully controlled by the pact. Not exactly. That is what makes them dangerous.
