Wait Namira Molag Bal whose the 3rd Daedra unless he's counting Dibella as one but I doubt it he's been fairly consistent with differing the Aedra and Daedra so i'm gonna guess it's probably Peryite it's not in Markarth but the mountains North of it but still maybe a new ordeal possibly Malicath with the nearby Orc Stronghold or maybe Mehrunes Dagon doing his thing again
