You have managed to think up some really nasty things to do to people, again.
I agree with Danny's pull-the-Juniors-out-before-they-die tactic, they're no good dead. But I think they should be going out and doing stuff more. Many reasons for that. Of course if they do that it's possible yhat someone might work out a way to stop them from using their escape, but that's going to take some time since it's hardly the standard teleport they're using. The one really obvious way I can think of someone doing it is picking Danny off early in the fight, which I'm sure the Purveyors will try next time, that could be got around by having Danny at the other end of the portal but then he'd not be able to join in the fight. How good is he at using his powers at range anyway? And could he use the Portal of Pretensiousness to improve on it?
There are a whole lot of quite nasty little plotlines you've got going on in the semi-background.
The Carnifax was certainly brutal, but from the moment he made his go-away-or-I'll-kill-everyone threat it was pretty obvious that that's what was going to happen. The prophesy at the end was interesting though, and the prophetess killing herself to stop him keeping his word was tragic, and a bit impressive too.
I don't know whether to be pleased or to argue that I only had a little bit to do with it.
