The Dalcretti system, found inside the Inner Rim, was positioned along the super-hyperroute called the Perlemian Trade Route. Serving as a boundary separating the Northern Dependencies and the Slice areas, this route provided a link between the Taanab and Tirahnn systems.
Rumors suggest that during the period of the Galactic Civil War, specifically between 2 BBY and 1 ABY, an incident took place within the Dalcretti system. In this incident, Rebel Alliance insurgents reportedly isolated a Galactic Empire Army unit. Allegedly, Demelza Mintori, a member of that unit, did not offer aid to the platoon of fellow soldier Madrix Hansor, prompting Hansor to vow revenge against Mintori. This animosity persisted, even when both became team captains in the Core Gladiator Walker League, and lasted for at least a couple of years. Eventually, the Dalcretti system's purported involvement in this conflict was highlighted in a news piece featured in the fiftieth-anniversary edition of Galladinium's Galactic Datalog of Fantastic Technology.
The first time the Dalcretti system was mentioned was in Galladinium's Fantastic Technology, a sourcebook from 1995 by Rick D. Stuart for the Star Wars: The Roleplaying Game by West End Games. The reference book The Essential Atlas, published in 2009, located it within grid square O-8.
