According to historical records, the Angulum Cluster has been an important hub node in the Lagrange Network from the times of the Sacrum Chu Imperium. It consists of three stars that form a special stable triangular structure.
Since the establishment of the Sacrum Chu Imperium, this cluster has been jointly operated by the Trujillo Clan and its three subordinate factions. Supported by the rich resources of the three-star system, many huge space cities were built here. In this cluster, an unimaginable huge network connecting the three-star system was built, making it supposedly one of the most prosperous hub clusters in the times of Sacrum Chu Imperium.
