After this one, the 30 Day Challenge schedule calls for me to pick favorite monsters (by type)--a task that keeps me busy for nine days. Given the importance of monsters to D&D, though, it seems an important category worthy of mulitple questions. On the other hand, I'm struggling just a bit to develop my answer to the question: who is my favorite NPC?
Sometimes with these types of questions, I'm not sure whether I want to answer in a personal way (i.e., from my own campaigns and games) or in a "populist" way; i.e., NPCs that are famous from modules, campaign settings, or novels or whatever, and are therefore known by many gamers all 'round the world.
In the end, on this one, I decided to split the difference somewhat. My friend Corey Reid ran a lengthy campaign using a fairly heavily house-ruled (mostly redacted to limit options, at least until such time as the players discovered more options) 3e game. He ended up posting a write-up of the game on the good ole ENWorld Story Hour forums. He later actually compiled this into a PDF, which can be bought from Lulu. Here's a link.
Yuek Man Chong is, again to make a reference to Glen Cook, very similar in many ways to The Lady, or Soulcatcher. She's not only insanely powerful, she's also actually insane. This is par for the course for any sorcerer who manages to survive long enough to practice their craft in Corey's Barsoom. But her integration into the game is what really works. She never overtakes it, even though I've heard Corey occasionally lament that he's afraid she might have. I think she's a ton of fun to read about, but only because the player characters are themselves interesting enough to go toe to toe with her (in a narrative sense, not in a let's roll initiative and take her down sense).
When we come back for day 15, it's my favorite undead. Which is difficult, I think, because I like the concept of undead (have I mentioned before that my game is as much horror as it is fantasy? Well, probably not recently enough.) However, I think D&D is guilty of ridiculous over-splitting and specialization of undead. Finding the one that's "just right" and does what I need is easier said than done.
