Crown Cluster

The Crown Cluster is an open cluster located in the Middle Shell of the Lareas Galaxy.

Overview

The Crown Cluster is a fairly large open cluster, with roughly 2500 notable stars and is 133 ly in diameter. The Crown Cluster has a notable Luminous Blue Variable at its center known as Narenna. The cluster is fairly unusual in that it has a large number of habitable worlds interspersed between its massive stars, and it seems to be an island of civilization surrounded by an unusually large area with no intelligent life. Its central star, Narenna, contains a vast dyson swarm that is likely the largest dyson swarm in the local universe.

The cluster also contains many intelligent species, which have united to create the Union of Narenna.

Strange things

The Crown Cluster contains several anomalous objects, including one of the only instances of a Porphyrion Star outside the Archurion Nebula. There are also many ruins of vast megastructures, as if a vast civilization used to control the cluster several million years ago. However, these machines have proven undatable. There are also many strange planets, some of which have bizarre signals eminating from them. The source of these signals are unknown.

Massive stars

The Crown Cluster houses some of the most luminous stars in the Lareas Galaxy, including the LBV Narenna, housed in a tight central cluster similar to R136 in the LMC. The small cluster is sometimes nicknamed the Lareas Jewel Cluster. The Lareas Jewel Cluster contains two LBVs (One being Narenna), 2 O type stars above 100 solar masses, a Porphyrion star, 11 Wolf-Rayet stars, a yellow hypergiant and an orange hypergiant, 16 red supergiants, three black holes and dozens of O-type stars above 40 solar masses. Hundreds of late O and B type stars reside in this cluster, and many more smaller, less massive stars. So it comes as a great surprise as to how many habitable worlds are located near this dangerous, radiation-ridden place. Just for context, here are some notable stars listed below:
