The Jidlor Marches constituted a sector located in the Mid Rim. As of 0 ABY, it was adjacent to the Marzoon, Tashtor, Halm, and Oriolan sectors along its southern edge, while its northern boundary was shared with the Freestanding subsectors. Situated to the east, the Jidlor Marches marked the Mid Rim's border with the Har Worlds sector of the Expansion Region. Within the Jidlor Marches was the Jidlor system, the native world of the sentient Swaze species.
The Online Companion on StarWars.com for The Essential Atlas, a reference book from 2009, introduced the Jidlor Marches. Modi created a map illustrating the sector, which was released in the 2012 StarWars.com article titled The Essential Atlas Extra: Sectors of the Mid Rim.
