I am about to start running this book for a group of F&D characters with about 260ish earned XP. They have lightsabers and I replaced the Silver Star scenario in the beginning of this book with an alternative session that had them ending up with Warde's Holocron.

I am looking for:

(1) any pitfalls or mistakes that are easily made and advice to adjust for them. Also, any thing that was weird and didn't fit.

(2) Good home brew scenes that were added

(3) How to best scale up the difficulty to account for saber wielding powerful PCs

(4) Alternate rewards to sprinkle along the way

(5) summaries of what happen in your games (redemption? slaughter? got stuck? etc)

Thanks everyone!

I just concluded this adventure with a mixed group:
1 Jedi
1 whannabe Jedi
3 more not force sensitive (smuggler, pilot, melee fighter)
However they have a huge lot of xp (at the end of the adventure they had 600 xp average)

Main problem i found is in Part III: it's way too easy to understand that "the wanderer" is Warde, and that spoils the adventure. Also they can force charge him into a trap, or like shoot from the starship or whatever.
So i did a little change:
- the wanderer was changed to a mirialan, so clearly he was not Warde
- i added a starship crashed, whose logs showed it as a freighter registered to imperial bureau (so clearly after the "death" of Warde)
- Warde disguised himself as a survivor of the ship crash (i named it "the survivor")

The Wanderer was a little crazy, he stated himself as "a keeper of the area" and "servant of Warde" and clearly thinks Warde is a dead spirit who talks to him. He's the real survivor but it state is just a chosen one, landed here long time ago 'cause his master, the spirit of dead Warde, needed him. He also can guide the PC to Warde sepulcral chamber, an antechamber of a massive sith temple where an almost embalmed corpse sit on a large stone. The corpse is not Warde's, however, and they can discover it with a simple roll (or just looking at it)

The Survivor is really Warde; he looks way older but also he can use some of their illusion power to make them not suspect anything. Narratively he can follow them unseen (thanks to illusion powers) or intercept them at any point (he knows where they ends up thanks to his foresight abilities). He jumped onto the PC while they where looking at "his" corpse, and then start fighting.
Both the survivor and the wanderer fought with the PC, ofc

If you search at some of my posts in the last few months you see a discussion about it

I also had to adjust the adventure to PC's XP level, so everyone was scaled up to knight level and more enemies added (ie more droids in the end of Part II). I did also some little adjustment based on their equipment (ie found a way to avoid them using speeders on Part I) but that's about normal for me

The real big elephant in the room is the adventure did'nt rise a real morality question for the Jedi (and less more for the not Jedi). You can change something here and there but is a more complex work and probably you can just adjust the things "on the run"
