The Triad is a cluster of 3 inhabited systems near the Confederation. They were discovered several hundred years ago by the Uhlani and developed an alliance based on similar religious beliefs. They have cool relationships with the human descended groups because they physically resemble evil entities from human myth and religion. The translated names of the planets are Wolf, Ram and Hart.
The inhabitants of Wolf are essentially the hybrid form of werewolves without the mystical or magical aspects. Silver is not found on their planet and when exposed to it they have an allergic reaction, furthering the human fears.
The residents of Ram resemble satyr or pan creatures of Greek myth. As this was also a model for Lucifer it creates an uncomfortable feeling with many of the humans.
The residents of Hart resemble "The Horned God" of Celtic and neo-pagan religions as well as one of the avatars of Vishnu in Hinduism.
The inhabitants of the Triad believe in the Great Old Ones. They believe the Old Ones of each planet created their races before being banished by the Elder Gods. There are several Old Ones worshipped on each planet but no duplication on any of the planets. There are several cults on each planet.
The Triad is a theocracy. Several priests from each world are educated in the beliefs of all the cults of their planets forming the High Priesthood. Three members of the High Priesthood (one from each planet) are elected to the Great Triad and share executive power.
The Triad is a high TL 5 society. They can't build or repair jumpgates or build jump engines. The have some laser techonology but not a lot. Because of their appearance and religion they have cool relations with most human descended cultures. They are known as the Nightmare Trinity and Evil Three in some places. They have good relations with the Acai Maj in part because they believe the Acai Maj planets are where additional Old Ones may be sleeping. They have become hostile to the Uhlani over the years as they have come to believe them to be agents of the Elder Gods who banished the Old Ones.
