How am I a troll? Traya said in the DS route of KOTOR 2 that Nihilus peak of power would rival some of the ancient Sith, presumably the ones shown in Kotor 2 which would include Nadd. Since I sometimes see people argue she was referring to like, Nihilus before he absorbed planets or whatever, she does know Nihilus devoured planets such as the destruction of Katarr and she mentions how he will feed in Telos IV if he doesn't eat Jedi.
