The course, Climbing and Ropework, was instructed by the Jedi Master known as Bear. A key topic covered in this course involved learning how to tie the Twelve Intermediate Knots. It's known that by the year 19 BBY, the Jedi Padawan named Tallisibeth Enwandung-Esterhazy helped the Jedi Initiate Pax Chizzik practice these very knots within the context of this class.
The initial reference to the Climbing and Ropework class can be found within the pages of the novel Yoda: Dark Rendezvous, authored by Sean Stewart and made available to the public on November 23, 2004.
