Lucasfilm confirmed that the upcoming trilogy will be set thirty years after the original trilogy and will feature a trio of young leads. Current speculation is that the new stories will focus on the next generation of Skywalkers, Darth Vader’s grandchildren. In Star Wars lore Anakin Skywalker has four grandchildren: Jaina, Jacen, and Anakin Solo (the children of Princess Leia and Han Solo); and Ben Skywalker (the son of Luke Skywalker and imperial dilettante, Mara Jade). If the new trilogy treats on the story of the Solo Twins, and the birth of Darth Caedus, it is arguably the most electrifying story in the Star Wars universe.
Those familiar with the expanded universe have already begun speculating that there is a strong possibility the Solo twins are candidates for at least two members of the “young trio.”
Like the other Jedi in the Star Wars universe, Jacen is tempted by and falls to the Dark Side although, as with Anakin in the original (sequel) trilogy, Jacen’s fall is only a means to protect his family. After marrying his high school sweetheart, Jedi Tenel Ka Djo, Jacen eventually transitions into Darth Caedus.
It is after his Darth Caedus transformation that Jacen’s Nazi-esque evil deeds reach their apex, including his relationship with, and eventual murder of, a force-sensitive cyborg named Lumiya, who carries a lightwhip instead of a lightsaber, and with whom he attempts to rebuild the fallen Empire.
