The Trifecta is the name given to the 3 interstellar coalition, often portrayed as the 3 hexagonal cell Orrery presented here.
These 3 systems are:
> Vebir - Top
> Ichbaal - Right
> Peltos - Left
Whilst 'The Trifecta' is used to describe the coalition as a whole, it originally referred to the jump gate network that connects the 3 systems together.
Concieved by the Arjorns of Ichbaal, The Trifecta was created to expand interstellar relationships, and to hopefully create an alliance, but when it first started out, many small conflicts broke out in all 3 systems.
After decades of conflicts and misunderstandings, The Trifecta finally stabilised, and after learning their lesson, the Arjorns stopped creating more jumpgates.
