The Gatekeeper was a holographic user interface of the Chamber of Speech in the ruins of the temple-city of Kaleth on the planet Tython. An ancient relic of the Je'daii Order—the predecessors of the Jedi—the chamber stored knowledge and information about the planet's past and the Je'daii's history. After the planet was abandoned following the Force Wars, the chamber fell into disuse, and the Gatekeeper shut down for over twenty thousand years. Assumption ends here.
