Thank you for all of the replies! There are so many things I hadn't thought of.
Except for the vampire touched, dhampir, vryloka. Great stories can be told of individuals from these ancestries, but not sure I want a half dozen families of Blades to be a normal neighborhood to find in each new town.
I do have some definite ideas about the plane of shadow. Less afterlife and more dreary dark reflection, with people going about their lives as best they can despite the darkness, despair, and monsters telling them what to do.Which cosmology is your game using, @Guang ?
I love the idea! Not for halflings though. Once halflings are mostly cannibal lifeshapers, or dino-riders, or world-stepping masters of shadow, it's really hard to get the down-to-earth community of the Shire feel back again. (Which I'd like to keep some of) I'm also imagining how terrifying Gollum would be if he could reappear suddenly after disappearing into a world of shadow.Birthright Halflings
Halflings seem to be harmless, good-natured folk, but they harbor hidden secrets. Most people assume that the name halfling refers to their stature, but only a handful know the truth. Halflings were once creatures who could pass freely between Aebrynis and the Spirit World.....Halflings can pierce the barrier that separates Cerilia from the Shadow Land by concentrating. This allows them to detect evil, detect undead, or detect necromantic magic with a high degree of reliability. Exceptional halflings can develop this ability to allow them to enter and exit the shadow world in places where the barriers between worlds are thin. Halflings avoid revealing these abilities to people they don't trust.
I could imagine some "civilized" ghouls who trade for "food" with a city above them. And as to the planar connection isn't that where their undead qualities come from?
Dhamfir works well too.
Wraiths
"Have you been working out?" might be thr scariest thing my undead neighbor might say to me. Working out how graveyards work when they are also larders and restaurants brings many changes to society as well. Same problem as with vampires.Vryloka, the kin you are looking for is the Vryloka!

I had forgotten about Fetchlings. Paizo's answer to Shadar-Kai, without the piercings and sado-masochism to keep from fading away. I really like what they've done with them in PF2e/lost omens. They seemed far too niche in the first edition, but now - a few slight changes, and you have a functioning society with a reason for being in the Prime Material, not too scary if a few families move into town, while being of value when it comes to recognizing and knowing how to deal with things of Shadow.
