Thanks for the comment. Glad you enjoyed the chapter. To answer your questions:
1 - Not really. Although he tells himself that it is for their own good and he does not want anyone to link him with the
Anakin Skywalker, it is mainly because he has no real reason to. Beyond his mother, he has nothing in common with these people.
2 - I pictured my Obi-wan as Alec Guiness, although a slightly fitter, leaner, meaner Alec Guiness. So yes, I guess he has aged slightly better, mainly from being more active than the Obi-wan who lived as a hermit.
That's a good idea for a weapon for this Empire. Of course, I've never said that there was a Death Star in this universe. Or any major weapon... So...
Thanks again for the comment!
