Curse of Strahd
Burgundria is a completely human empire. If there were tales of Elves or Dwarves that once lived in the world, it is centuries ago and they are dismissed almost entirely as children’s stories.
Variant human is highly suggested for everyone. They are a great versatile race and picking out a feat is a blast! So go for it! Dwarves, halflings, and ½ Elves are a 2nd best option. Try and avoid the really high fantasy races altogether if possible (Elves, Dragonborn, Goliaths, Gnomes, Aarakocra, and Half Orcs). An exception for one or two people is the Tiefling and Aasimar, but possibly think of your physical appearance as much more subtly showing your heritage. No horns, tails, and wings, but rather tieflings might have a tiny pinpoint of red light in your eyes, shadow that seems to never leave your face, while Aasimar might have a faint pearly sheen to your skin, or eyes of deep violet.
