There was no reason in her mind anyone should turn down such an offer. Certainly it took away a good deal of free will, the fae could trap you tighter than a chinese finger trap, but it also meant gaining power. And who did not want power?

"Werewolves?" She looks displeased with the thought of dealing with werewolves. She knew a flighty fae who loved turning men into dogs, hellhounds really, but Mab had never acquired that taste. One had to made due with options available though. And if they were willing to work in tandem against Vampires and witches that thought it was their duty to police the ways between worlds Mab would simply have to suck it up. And perhaps invest time in creating a deodorizing spell. "You believe they would be amenable to assisting? They do tend to be touchy about other races, no?"

Her eyes widened a little at the question. "Certainly not." She wasn't going around giving witches her name. They must owe her a favor first. It would keep them careful about abusing the summoning. "Not in London, no."
