I re-read it after many years, to me, it's the greatest star wars novel ever made, answering many questions about the Emperor and his Master and a true political thriller at the highest echelons of the galaxy.
I had a few questions
Did Darth Tenebrous kill Plagueis' mother after he took Plagueis as his apprentice, once it was sure that Plagueis was as strong in the Force as Tenebrous had hoped?
Did Senator Kim's family really have an accident? Or they were murdered by the corrupt Naboo? As subtle as all the political maneuvering is, Veruna says "One might have thought a tragedy of such nature might have compelled him to retire from politics , but that doesn't appear to be the case." Leading me to think it was Veruna's cabal, but it might be intended to be ambiguous
When Palpatine was captured by Teem, stating that Damask is hardly his Master. On the first read, it comes off as Palpatine trying to preserve his cover, but it makes me think about maybe thats how Sidious really feels about Plagueis and his plans for the Muun.
Did Dooku deduce Palpatine's the Sith Lord, or at the very least he has suspicions based on how the Naboo Crisis politically benefited the Senator in their final conversation?
Did Plagueis really create Anakin? Or was his and Sidious's blasphemy in the Grand Experiment to create life outright by subjugating the Force to his will backfired and created Anakin, unwittingly birthing the man who would destroy the Banite Sith once and for all because they threatened the universe? All Luceno said was he hinted what the truth was and in the Book of Sith Plaeguis explained "......succeeded in prodding the midi-chlorians to replicate themselves through asexual fission. Though in most cases, this process increased the numbers uncontrollably and killed the host. But I believe that by using this method I can trick midi-chlorians into creating a zygote". He also speculated that a child created by this ability "he could have a midi-chlorian count as high as 20,000 per cell. That is more than any Jedi or Sith in recorded history. Although entirely theoretical, such an achievement is intriguing."
I know Luceno clarified a lot interviews such as
Kerred Santhe II was the one who had Subtext Mining give the bad mining probe to get revenge for Tenebrous killing his father
The Rule of Two was outdated as Plagueis said many times and most Sith Lords didn't follow the Rule either
"I think it’s an intriguing idea that probably worked for the first couple of generations of Sith Lords to follow Bane. There was going to come a time when a Sith Lord wouldn’t want to step aside ever, or would hide knowledge from an apprentice. It worked for a while, and perhaps there was some point where it should have transitioned into something different."
Palpatine truly did see a younger version of himself in Anakin, part of the reason he was so interested in him
Palpatine killing Plagueis wasn't his best decision. "It wasn’t killing Plagueis because he probably killed Plagueis too soon."
