AKA I Like Big Bulettes by Sir Bargle Mix-a-lot.Bargle's Big Book of Bulettes
Baba Yaga's Tales of the Fey.Yeah, I'd expect Szass Tam or Vecna as the author of a book about undeath. I imagine we'll get one about the Feywild at some point, but I dunno what named scholarly NPCs would fit for that.
OoooooBaba Yaga's Tales of the Fey.
I would love to see her on the undead book, and Nissa on a book that is all about Primal magic, nature spirits, and the Fey. And hopefully finally makes dryads/treants playable in 5e.Lilliana is the type of hero who looks like a villain, but she's clearly on the good guys side at this point.
I think she would be a great named character for the Undead book.
