"The High Republic Padawans really run the gamut in terms of skill, devotion, and personality," Lucasfilm Publishing Executive Editor Jennifer Heddle told
StarWars.com. "Some are reluctant to seek out adventure while some are perhaps a little too eager; some are extremely talented in the Force while others maybe have to work a little bit harder. We wanted to showcase a wide range of young people in the hopes every reader can find someone they relate to."
Burryaga Agaburry
"Burryaga is one of the few Wookiees to travel from the lush forests of Kashyyyk to study in the ornate halls of the Jedi Temple on Coruscant,"
Light of the Jedi writer Charles Soule explained. "While he is skilled with his two-handed lightsaber, it is Burryaga’s natural, effortless ability to sense the emotions of others that sets him apart from other members of the Order."
Reath Silas
"Reath’s had a somewhat privileged apprenticeship because his master, Jora Malli, is a member of the Jedi Council,"
Into the Dark writer Claudia Gray said. "That means he’s spent a lot more time on Coruscant, in elevated diplomatic meetings, and that kind of thing — so the frontier is going to be a huge transition for him. Reath’s learning what he’s really made of."
Lula Talisola
Daniel José Older, the writer of IDW Publishing's
The High Republic Adventures, described Lula Talisola as being "all about the Jedi Order." "She loves it, can hardly wait to get Knighted, and wants to be the best Jedi that ever was. Besides being amazing and top of her class with a lightsaber, she’s loyal and compassionate and looks out for her two best friends, Farzala and Qort. Especially when they’re causing mischief."
Bell Zettifar
"Bell Zettifar is apprenticed to the legendary Loden Greatstorm, and he hopes he survives the experience," Soule noted. "He and his master are currently stationed at a Jedi Outpost on the ore-world of Elphrona, deep in the Outer Rim, where they work to keep the peace and spread the light."
