Arca Jeth's Praxeum, also known as Master Arca's Training Center, functioned as an academy utilized by the Jedi Order and was situated on Arkania. Arca Jeth, a Master, acted as the administrator of the facility and resided there throughout the duration of the Old Sith Wars.
Master Jeth founded the facility deep within Arkania's wilderness, positioning it at a distance from the diamond mines that were prevalent across the planet. The praxeum was designed to accommodate a large number of students, sometimes exceeding twenty, for training and lodging. Jeth instructed his students in Lightsaber combat, Force techniques, meditation, and diplomacy, employing both ancient training droids and the native wild Arkanian dragons as training adversaries.
Numerous Knights received training at the praxeum, including figures such as Ulic Qel-Droma, Cay Qel-Droma, and Tott Doneeta. During the Great Sith War, the Jedi High Council recognized Padawans Krynda Hulis and Barrison Draay's successful completion of the Jedi Trials and conferred upon them the rank of Knight. Jeth, along with the Knights stationed at the praxeum, formally knighted the pair, while excluding Padawan Haazen, as he had not passed the Trials.
The praxeum building, constructed from lumber and stone, consisted of two stories and featured a main hall that served as a venue for knighting ceremonies, training matches, and various other events. A small porch wrapped around the main structure. A courtyard, adorned with carvings and artwork etched into its stone walls, was situated nearby.
