>>107388280Let me see what I can give you that's not spoilery.
The story only mentions two padawans, Rael Averross (from Master and Apprentice) and Qui-Gon, so no Vosa. I can't remember if it confirms that he only had those two but I think I remember them mentioning he hadn't taken another one after Qui-Gon. He does become a lightsaber instructor, though.
Dooku and Sifo-Dyas were younglings together and basically best friends for life. They called each either Doo and Si when they were kids but grew out of it later. Also Tera Sinube was the one watching their clan, sort of like how we see him hanging out with the younglings from TCW.
Similarly, Qui-Gon, Ky Narec and Ima-Gun Di are part of the same youngling clan.
Dooku actually has pretty strong animal kinship powers, and even takes care of a Jedi's convor while she's away. Apparently Jedi are allowed to have pets or something, that part isn't really made clear.
Dooku actually manages to get a seat on the Jedi Council, and he's still on it at the time he decides to leave. He's also the Jedi representative in the senate, which I didn't know was an actual job.
It doesn't specify exactly when he left, but going by Master and Apprentice, Dooku left at least 7 years before the Battle of Naboo. This was already kind of implied by the timeframe in TCW which had him killing Sifo-Dyas and getting involved with the Kaminoans before the Battle of Naboo.
Apparently Jedi padawans are chosen once a year. They hold sparring duels while prospective masters watch, and each year they change up the format, like having the duels blindfolded or underwater. If you don't get chosen, you're held back a year.
The gladiatorial arena from Genndy Wars is back, and it's now canon that this is where Dooku finds Ventress, though the scene plays out a little differently.
That's all I can think of that wouldn't really count as spoilers.
