Very much appreciate the feedback S-Snake88. Glad to know that I’m hitting some good checkmarks as far as a solid Star Wars story. To answer your questions:
Nellith’s lightsaber is green. I really dig the idea that Luke’s color becomes an internal callback to a prominent Jedi of the past, and his role in bringing Anakin to the light recalls Nellith finding her way back.
The large scale station is not the Death Star, though in a broad sense the latter clearly drew upon designs and specs from the former. Its less than half the size of the Death Star, with the general concept being that the nature of Republic designs and schematics are already subtly reflecting the future Empire.
Agewise its roughly like this circa episode I:
-Anakin and Carima are in their mid 20’s.
-Kenobi and Darelda in their mid 30s.
-Bail is late 30s with Crayde around 40.
-Phakerem, being both a Mandalorian prone to stitching herself together with various parts (a character trait that’ll expand upon in future revisions of Episode I and II) is fairly long lived, and is at least 200.
-Palpatine is middle aged… seemingly.
On that last point its never overtly said, but there’s hints that Palpatine is a bit older than quite anybody realizes, and he’s possibly been waiting for some time for an opportunity to gain a high position. Near the end of Episode III when all possible opposition against has dissipated, in private his face begins to show signs of being older and decrepit, suggesting that illusions about maintaining a more youthful facade are no longer necessary now that he’s achieved absolute power. Come ESB and ROTJ, we see that he’s wholly embraced what his age and use of the Dark Side has turned him into.
