‘Here’s why you can’t exterminate us, aruetii. We’re not huddled in one place—we span the galaxy. We need no lords or leaders—so you can’t destroy our command. We can live without technology—so we can fight with our bare hands. We have no species or bloodline—so we can rebuild our ranks with others who want to join us. We’re more than just a people or an army, aruetii. We’re a culture. We’re an idea. And you can’t kill ideas—but we can certainly kill you.’
The Solo twins Jacen and Jaina are born in the Thrawn trilogy. Anakin (Solo) is born in Dark Empire.
Jacen and Jaina first join the adventures as mere 2 year olds in the Jedi Academy trilogy.
Both they and Anakin take on much larger roles, while still younglings under the age of 10, in the Crystal Star and then the Corellian Trilogy.
Being the grandchildren of Darth Vader/Anakin Skywalker, niece and nephews of Luke Skywalker and children of heroes, they are constantly in danger of kidnapping. Just as Anakin Skywalker, all three children have a tendency to find themselves in positions to influence Galactic events, often without realizing they are doing so.
