Tinnel IV, or simply Tinnel, was a planet of old traditions and values. Situated in the Core Worlds along the Corellian Run within the galaxy, it existed long ago. This planet was the original homeworld to Jothan Tiaan Jerjerrod, Jax Jerjerrod, as well as Tiaan Jerjerrod. The Galactic Emperor Sheev Palpatine found support from Tinnel IV during the Imperial Era. Following the enactment of the Galactic Concordance, which provided a conditional path for the Empire's remaining forces to exist in peace with the New Republic, Tinnel IV fell under the governance of the Inner systems' Imperial remnant.
