Sure as I'm not playing this season. Shin Malphur killed Dredgen Yor at Dwindler's Ridge. I've read that story so many times I know every detail of it. Read the lore. It's one of the best stories of the game by far. As I was saying, Yor is dead, period, as he parted ways with his ghost on Mars before the duel with Shin, which he lost. Therefore the Drifter is just that, the Drifter. He was one of the Dredgens, but not THE Dredgen.
