Shadowfell Walker (5e Race Variant)
From D&D Wiki
Like elves who ended up in Shadowfell, humans have fallen to the nebulous realm as well. Similar to how the shadar-kai came to be, shadowfell walkers are humans who have become warped by the energies of the Shadow Realm. They become specially attuned to its energies and the environment of the place, becoming survivors of the dark in a place where they qualify as prey for many.
