Introductory note: As I was taking visitors and new personnel for the Chapel with me to Seclusion during my visit last week, I prepared a primer for them about Anoikis. This was also useful for me! When I was young, nobody knew of the existence of Anoikis, and it was a surprise to me when I first came back from the asteroid monastery to worldly matters. So, I decided to put this primer in my own log for later reference.
Today, I will start with the first part, geography, and tomorrow I will compile the next part, history.
Geography
Anoikis is a star cluster situated about 1500 light years from Amarr, in what would be called the south-western direction along our cluster's plane. Just like our cluster, it is a circular, disk-shaped cluster. It contains about 2600 stars, so half that of our own cluster of known worlds, grouped in sub-clusters. The stars have been named according to their stellar catalog number, starting with a "J" and then a number. That is why Anoikis is sometimes also refered to as "J-space".
The stars are categorized in classes, ranging from class 1 ("C1") to class 6 ("C6"). The higher numbers are more dangerous as their original denizens (discussed below) are more entrenched. Many stars are unusual: among them are plenty magnetars, black holes, red giants, pulsars, and so on.
The stars are grouped in constellations and regions, but there are no jump gates, nor fixed routes connecting them. The regions' designation start with a letter ranging from A (containing the C1 stars) up to F (containing the C6 stars).
The map above shows the shape of the Anoikis cluster. Coordinates are in light years, putting Amarr at the origin. So, the center of Anoikis is about 1000 light years south and 825 light years east of Amarr. The two coordinate lines in the graph point out Seclusion's location.
The colors refer to the class: C1 purple, C2 blue, C3 green : these systems always have wormholes that connect to our own cluster. They are the entrance gate, and probably were the first to be colonized. From there it goes outward to C4 yellow, C5 orange, and the last subcluster C6 red.
