I like the idea of Jedi having families and children like normal people, especially since it makes their extermination by Vader a thousand times more tragic.
I actually never knew that this was a thing.
I only read of it in Children of the Jedi, an otherwise underwhelming book.
Most of the old Thrawn trilogy works for me (sans Luuke), and I really liked the inclusion of truly alien Celestial technology in Corellia’s Centerpoint Station for example. Really, the old EU had a lot of stock and unremarkable stories but was built on the foundations of a more interesting universe than the new EU.
