In the Curse of Strahd adventure, there are a unique subrace of elf called dusk elves, and the adventure has this to say about them:
Dusk Elves. The dusk elf race is all but forgotten, and the few survivors live in secret places such as this. They have dark skin and hair, but otherwise they are similar to wood elves (as described in the Player's Handbook). -- p. 119
As punishment for depriving him of his bride, Strahd butchered all the women in the dusk elf tribe [...] -- p. 232
Patrina's own people stoned her to death to keep Strahd from claiming her as his wife. Strahd was upset that the dusk elves had taken Patrina from him. After securing her body and entombing it in the catacombs of Ravenloft, Strahd sent Rahadin to punish the dusk elves. Rahadin slew the female elves so that the males couldn't breed. -- p. 237
So it seems that, during the time that the adventure takes place, there are no female dusk elves left alive
(with the exception of Patrina if resurrected, see p. 90 and p. 196 for more info of Kasimir bringing Patrina back from the dead)
but then, in DDAL04-06 The Ghost, there are female elven characters such as Derali (p. 11) and the "very young female [elf]" (p. 13); however, their subrace is not specified. There are other examples of elves (without a specified subrace) in Barovia presented in other AL adventures, but this is the first one I've encountered with female elves included and even named (even included on the "Appendix: NPC Summary" page):
Derali (DAY‐rah‐LEE). Female elven druid from the Quivering Forest. Searching for missing elves abducted by ettercaps. -- p. 23
As an additional piece of information from the AL adventure, the Adventure Overview on p. 8 includes the following:
Part 1: The Hungry Forest. The adventurers encounter a party of nervous elves from Greenhall.
However, I don't know what "Greenhall" is, or whether that invalidates some of my logic leading me to believe that these elves are dusk elves. The AL adventure itself (and therefore, meeting the elves) does take place in Barovia, however.
As far as I'm aware, there are no other elves in Barovia besides the dusk elves (certainly no other elves besides dusk elves appear in the Curse of Strahd adventure), which implies that these female elves (and for that matter, the other elves-without-a-subrace included in these AL adventures) are dusk elves, although it contradicts the quotes above from p. 232 and p. 237 that says they were all killed.
On other other hand, the quote from p. 232 also says "the dusk elf tribe" and p. 119 says "live in secret places such as this", so this could be read to mean that there are other tribes of dusk elves in Barovia that had nothing to do with the events of Patrina (presumably not known about by the now-male-only dusk elf tribe), and therefore could still have females. However, this isn't expanded on in Curse of Strahd, and is only hinted at in these AL adventures.
So I can only see the following possibilities to resolve the apparent contradiction in the above information:
- The female elves in the AL adventures are dusk elves, and they were just a separate tribe that had nothing to do with the Patrina incident;
- The female elves in the AL adventures were some other kind of elves (say, wood elves or something) and there are, indeed, no female dusk elves after all;
- Whoever wrote these AL adventures made a mistake...
Am I missing something? Which of the above is true (or is there an "option 4")?
