A good follow up to Mercurial is actually A Killing Glare, as Kyle Morgan and Perianwyr make a return appearance in those.
Funny thing about Elven Fire. I've used Elven Fire in various games probably half dozen times. But I've never actually run the adventure itself. Instead, I have this adventure that takes place during the events of Elven Fire. An NPC team of runners is doing the Elven Fire stuff, and failing. So mass gang warfare breaks out across the city, and eventually the National Guard gets called in.
And meanwhile, my PCs are trying to find the daughter of a rich corp exec who has run off with her boyfriend, who happens to be a mid-level member of one of the mid-tier gangs that has gone to war.
There are, of course, a few twists to that to complicate things. And it gives me an excuse to throw in the Steppen' wulfs and just go crazy.

It also lets the PCs break out the big guns, since the entire city is so engulfed in flames (figuratievly and literally) at this point that no one notices some heavy gunfire and explosions.
