So, let's start short term. In the near future, Taylor would have soon begun having actual conversations with Darth Occulus. Occulus has been spending her time thus far subsuming Taylor's shard and bending it to her will. Once she opened up, you'd get your training to speed up, as she'd be available to help you.
She'd also offer you the ability to steal shards from parahumans. This would require defeating the parahuman to start the process, obviously, and would come at the cost of losing Taylor's accelerated training for a couple of weeks, in exchange for getting access to the parahuman's unique power. It would also come with the hidden downside that it's technically Occulus getting these shards, not Taylor. This means that if Occulus ever got a new body for herself, then Taylor would lose those powers and Occulus would be massively buffed.
On the Star Wars side of things, the attentive reader may have noticed that there was a "meteor crash" mentioned in the Interludes. This was the Jedi Consular showing up (specced as a Jedi Shadow). She'd be working with Dragon in the short term. You'd start hearing in the future that the Dragonslayers were taken down, and then later, perhaps the Slaughterhouse 9 as well. Eventually she'd meet up with Taylor and Occulus and we'd get into their history together as well.
Returning to the idea of the Shards, I'd planned to change the lore around the Entities a bit to fit into Star Wars. In SW lore, there's a group of sentient force sensitive crystals that have themselves implanted in Droid bodies to move around. The Iron Knights. The Entities would be a group of similar crystals who had developed something of a hive mind -- and then saw the threat of the Emperor devouring the galaxy and decided that they needed to figure out how to fight him.
On that note, the end game wouldn't be Scion. The Emperor would show up, wearing the body of the Jedi Knight. Essentially, the Emperor won his gambit in Eternal Throne and is now the "hero" of the galaxy, hanging out in a new body until he gets bored and decides to eat the galaxy again. Earth Bet would gear up to fight Scion, and the Emperor would show up and kill Scion.
End game is figuring out how to put down the Emperor.
If anyone else has any questions on where certain ideas would have gone, feel free to ask.
