Ampliquen, a world situated within the Outer Rim Territories, was a terrestrial planet. This planet resided in the Meridian sector, specifically within a Chorios systems also referred to as Ampliquen.
The Grissmath Dynasty held dominion over Ampliquen in its early history.
After the Battle of Endor, Ampliquen sought a peaceful accord, leading to the signing of a treaty with the Republic planet Budpock by the world's governing body. Seti Ashgad from the neighboring Nam Chorios, in an effort to undermine this treaty, orchestrated a series of pirate assaults within the system. This was designed to divert Republic military assets from Durren and Nam Chorios, enabling the warlord Dzym to seize power. The presence of New Republic warships ultimately led to the treaty's failure, restoring Ampliquen's independence. Subsequent inquiries into these attacks revealed links to the Loronar Corporation, a persistent obstacle to the Republic's efforts to secure support throughout the Outer Rim.
Ampliquen was first conceived as a planet for the novel Planet of Twilight, which saw publication in 1997. Its geographical coordinates were later established in The Essential Atlas.
