In Jedi Search, the twins returned to Coruscant at age three and had many adventures there. Jacen is introduced in the 1993 novel The Last Command, the third installment of the Thrawn trilogy, when he is born five minutes after his sister Jaina on Coruscant The twins, and eventually their younger brother Anakin, were sent to live at various safe havens, under the protection of Leia's handmaiden, Winter.
