A training course existed on the Outer Rim moon of Ajan Kloss. This course, found in the Klosslands, served as a location where Leia Organa taught her Padawan, Rey, about the Jedi path. This instruction occurred during the First Order-Resistance War in 35 ABY. During her time on the moon, Rey practiced on the course repeatedly, improving her abilities with the Force by battling both the wild jungle environment of Ajan Kloss and a collection of Marksman-H training remotes. These remotes were left by Organa's deceased brother, the Jedi Master Luke Skywalker.
