Behind the Scenes
This Jedi was the creation of artist Joe Corroney, who modeled her after fellow artist Jan Duursema, from which the character also takes her name. Note that, though the character is official, her name is not; she is referred to only as "Jedi that resembles Jan Duursema" in Leland Chee's notes.
