The Andalia system existed within the Lorelli Reach, a region found inside the Hapes Cluster. This cluster was situated in the Slice area of the Inner Rim. The Lorell Route hyperlane provided a connection between it and both the Lorell and Sennex systems. Famously, the system of Andalia was where the clothing item called the Andalian cloak first came from.
The reference book The Essential Atlas, which came out in 2009 and was written by Daniel Wallace along with Jason Fry, marked the first appearance of the Andalia system. It was located in grid O-9 within the book.
