This is why he asked if it would be a good idea, Skulduggery. But the fact Skulduggery even has to take a breath says something, and so Ghastly braces himself, even though he was more or less braced already.

"You sent her to the Faceless Ones," Ghastly repeats, blankly. That's... one solution. If Darquesse was as bad as she seems to have been, then it follows that they'd have to resort to something drastic, and allowing unkillable horrors to deal with unkillable horror probably works, but it's still a bit horrifying.

Why would anyone have built that into the Accelerator. Ghastly shakes his head slowly, almost disbelieving the sheer volume of bad that happened after. "I can guess," he says quietly. "I... how many of us are left, Skulduggery?"

Not an answer he wants, but one he probably needs.
