I never read the post-ROTJ novels when they came out, and at this point there's way too many for me to even attempt reading them. But i can still appreciate all the cool characters from them and the comics.
Tahiri Veila was the granddaughter of a Jedi of the Old Order, Veila was born on the planet Tatooine to a pair of moisture farmers, Tryst and Cassa Veila. After the deaths of her parents, an orphaned Veila was adopted by the leader of a Tusken Raider tribe who raised her as one of the Sand People. Around 22 ABY, Jedi Master Tionne Solusar discovered Veila's connection to the Force and brought her to the Jedi Praxeum on Yavin 4. She then formed a friendship with a fellow Jedi Initiate named Anakin Solo, a grandson of the Jedi Chosen One Anakin Skywalker. The experiences of her childhood on Tatooine ultimately caused Veila to develop a particular trait that she retained well into adulthood: a phobia for footwear. After spending her first years on a surface covered mostly by hot sand, Veila reveled in her new-found freedom as a Jedi to walk barefoot whenever she pleased. She loved the sensation of feeling the cold surface of the Great Temple on Yavin 4 with her feet. With few exceptions, Veila spent most of her young life without shoes.
Agent Aleksandr Kallus
Alexsandr Kallus was a human male revolutionary who served as an agent of the Imperial Security Bureau, operating number ISB-021, before becoming a rebel spy in the formative days of the Alliance to Restore the Republic.
As an Imperial operative, Kallus was a firm believer in bringing order to the galaxy. He worked to suppress dissent on numerous worlds, fighting against the insurgency of Saw Gerrera on Onderon, participating in the genocide on Lasan, and leading the hunt for the rebels of the Ghost on Lothal. His efforts on Lothal were largely unsuccessful, leading to an escalation of force against the growing rebellion in the form of both Grand Moff Wilhuff Tarkin, Governor of the Outer Rim Territories, and the Sith Lord Darth Vader.
