About "collector devils": Cambions (half-devils) are interesting to me in particular, since they cannot advance up the hierarchy the way other devils can. For those unfamiliar with the lore of the Nine Hells, devils’ forms change to something more powerful as they’re promoted or demoted. (Lorcan and Sairché’s mother was demoted from an erinyes to a succubus in the first book). Cambions don’t have that ability, and so they have less to gain and more to lose by playing the hierarchy’sgames. If they displease the wrong archdevil, they can’t be demoted into a lesser form: they can only be killed (and then presumably their souls return to the Nine Hells and possibly arise as new devils, so I guess in a sense, they can advance up the hierarchy…just not in a very pleasant way).
There are surely more examples of these sort of “micro-status” actions in the Hells. I’d put them vaguely on par with achievements in video games. You’re not going to win because you find all the tokens, but you can definitely lord it over anyone else who seriously plays that game. And there are definitely other benefits to collecting warlocks, intentional or unintentional.
* Temerity is the first of Lorcan's other warlocks that shows up "on-screen." I'm inordinately pleased at her "virtue name." Margarites and Zeal Harper join Bryseis Kakistos, Caisys the Vicelord, Titus Greybeard, Caldura Elyria, Phrenike, and Nicodemus to make eight out of the Toril Thirteen.
* The Harper agent in the taproom, "Lady Hedare," is Tennora from my first book The God Catcher. Because originally, this book was supposed to be about Tennora--they asked me for a human wizard story. I found I couldn't deliver--I liked the book I was going to write, but not where I'd have to take the series they wanted. So I convinced the Powers That Be to take a chance on a tiefling warlock book. But here is a little glimpse of the Adversary That Wasn't. Tennora is a Harper with a slightly scandalous lover, and she still works for Nazra Mrays.
*Lord Vescaras Ammakyl also would have been in that book, although he didn't come together as a charater until The Adversary. I just had a picture in my mind of a Harper agent who was a half-elf nobleman, looked like Paterson Joseph and acted like a kind of stuffy James Bond. So I went to Ed Greenwood and asked if there was any way to make this work (and maybe also make him a wine merchant...). He offered up the Ammakyls, whose matriarch in the 2E Waterdeep boxed set was drawn as an elf. Some rough geneological calculations of the intervening five Lords/Ladies Ammakyl and their Turami and elven spouses, and here's Vescaras, son of Lord Lroster Ammakyl, who is married to (an elf) Lady Iluendrue Ammakyl. (His younger sister, Jadzia, is named after said matriarch and the elder is the Ammakyl heir.)
