The Epitadeus System's only colonized planet is Epitadeus c, more commonly known as Hope.
The Epitadeus system is a binary system within the UNSC inner colonies region of space. It should be noted for Hope, it's only planet colonized by the UNSC. The Epitadeus system is among the few colonized star systems to have been discovered relatively recently and by accident, as it's stars were obscured from view on Earth. It was never part of any human constallations.
