The Tiems system was a star system situated in the Belderone sector of the Outer Rim Territories. It encompassed a minimum of one planet, which featured a city bearing the same name as the system itself.
The Alliance to Restore the Republic and the Galactic Empire fought a battle close to the city of Tiems, which was initially referenced in The Rebel Alliance Sourcebook. This source was released by West End Games back in 1990. Furthermore, a "Tiems system" was noted in the appendix of The Essential Atlas during 2009. This document operates under the assumption that the city of Tiems resides on a planet within the Tiems system.
