The Skyrim account changes history though. The Nightingale left her without mating her. She didn't become pregnant till during the Imperial Simulacrum; and that was most definitely Jagar Tharn. He was (then) assumed to be the Nightingale who tricked her into giving him access to the Staff of Chaos.
The Skrim account on Barenziah has jumbled her history to suit their storyline for the Nightingales, but before Skyrim came out the history and dates were clear on it.
True. Bethesda often does that. Otherwise, I am not certain. In TES V 'lore' it was Dralsi Indoril with Karliah being her Granddaughter.
But also keep in mind how they had two different versions of Barenziah as well.
According to
The Real Barenziah, Book V he wasn't Nightingale either. She saw him and Uriel Septim in a Vision when she was before Jagar Tharn in the Imperial Palace. She also had a suspicion:
QUOTE
Something had piqued her interest. "Symmachus. Could this Jagar Tharn have been the Nightingale, disguised?"
Something which Symmachus shrugged off as Jagar Tharn didn't have 'human blood' in his ancestry.
But, that doesn't take into account the power of Illusion spells which is heavily intimated that she was under a 'Charm' spell, and impersonating the Emperor, he certainly was more than capable.
But, this version was written by
Plitinius Mero whom the Nerevarine meets in the expansion 'Tribunal' for MW. Any information he would have learned and uncovered was still subject to Barenziah's manipulations. Though she did take him under her wing to protect him from the Imperial Family.
So it would appear the Dev's intentionally left it ambiguous to let the players draw their own conclusions, which they are more or less famous for. Disappearance of the Dwarves and the multiple possibilities for it being among those.
But, yes I know what happened to the Dwarves.
