Allana Djo Solo is the daughter of Jacen Solo and Tenel Ka Djo, Queen Mother of the Hapes Consortium, and heir to the Hapan throne. She was born during Troy Denning's Dark Nest trilogy (2005), where Tenel Ka's relationship with Jacen was developed as a secret running through all three books, and she is Legends only.
The most exposed child in the galaxy
Her parentage is a state secret twice over: revealing it would destabilise the Hapan succession and mark her as the child of the man who becomes Darth Caedus. The Legacy of the Force and Fate of the Jedi sequences hide her with Han and Leia under an assumed name, which produces the odd, affecting spectacle of two retired revolutionaries doing the school run.
Why she matters structurally
Legends needed somewhere for the Solo line to go after it had killed Anakin Solo and turned Jacen. Allana is the answer: a fourth-generation character who inherits the Skywalker-Solo problem — enormous power, enormous name, no consent — and is written young enough that the books never resolve it. She is the closest the old continuity got to a hopeful ending for that family.
Continuity
Legends only, and one of the clearest examples of what the 2014 reset discarded. Canon's Solo grandchild is nobody; the line ends with Ben.
