Al had followed Isaint out to witness his Satanic congress. The demon was small, and attempted to hide its malevolence with a modicum of cuteness. Al wasn't fooled.
Isaint laid things out for the imp. Al wondered how he knew it was really from the lesbians. Probably it was a gut thing. And if he didn't trust the gnome, he trusted the German ork's gut.
The thing listened impassively, and with a delay of only a few seconds, spoke again, as if relaying words. The ceremony must be on the Isle of Lyonesse. And then it held up a miniscule hand as Isaint started to object. My Mistress is aware you may have concerns, but since you request a face-to-face meeting in any case, then your objections are best aired in that setting. My Mistress herself is too closely watched right now, since the trouble in the gardens. But her beloved Cara will meet you. My Mistress will make the arrangements, and I will return with news.
Then the thing was gone. Not knowing how long the wait would be, or when the meet might be. they started getting ready for their errands topside - Robyn giving instructions for Lady Karasu in the care of Iris and Jackhammer, Isaint going over his elaborate plans for securing and fabricating explosives, and Al pretending to listen to him while some new tricks he could teach Spike.
Before they could consider actually leaving, however, the runt-spirit was back.
Go the fourth level of Nightside Market, a well-known shop called Pretty Poison. She will see you there. Do not acknowledge her when you see her, but follow discreetly and she will lead you to a place where you can converse freely. Sadly, she must be very judicious, and can rely on none of her own House to assist her. They will not know you are expected of her, and in fact would likely try to hinder you if they did know. So tread lightly, for many are her kindred in that part of the market, and you are ill-loved by them, whatever the formal rulings.
And then the spirit was gone.
"Well, there ya have it - wherever we least wanna go, that's sure 'nuff where we's goin'."
