Dusk Elves

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). One of Strahd’s old brides, Patrina Velikovna, used to live here. Her brother, Kasimir Velikov, still does.
The dusk elves reside in small homes built into the hillside and are mostly self-sufficient. They are skilled trackers, and many of them are away from camp when the characters arrive, helping the Vistani search for Arabelle. Strahd has tasked the Vistani with keeping an eye on the dusk elves, and the dusk elves know they aren’t safe in Barovia without the Vistani’s “protection.” Strahd has also forbidden the Vistani from helping the dusk elves escape his domain.
There are no women or children among the dusk elves. Strahd had all the female dusk elves put to death around four centuries ago as a punishment for Patrina’s murder. Thus, the remaining elves can’t procreate. A broken people, they are aware of the vampire’s absolute hold over the land of Barovia. They keep a low profile and have no desire to incur Strahd’s wrath again.
