Dehau EG-Y g9 1 is an M-class dwarf with a stone ring 1,525,400 km wide and a mass of 56,250,000,000,000 Mt, located 14,062.2 light-years from Sol in the Temple region. This star orbits a black hole with a mass of 9 solar masses.

Like most stars of this class, it is a low-mass star with an absolute magnitude of 11.37.

The second star and the third in the system, a T-type, has metal-rich rings with a width of 1,113,100 km and a mass of 34,622,000,000,000 Mt.

This system houses two ringed stars which orbit the primary black hole as its satellites. The first one is a class M red dwarf star, with rocky rings.

A class II gas giant orbits it as its sole satellite, with rocky rings as well.

The second ringed star in the system is a class T brown dwarf star. Unlike the other two, this one has metal-rich rings, and a diverse variety of bodies orbiting it. There is a Water World (2 c) with a thin carbon dioxide-rich atmosphere (a candidate for terraforming), while its "neighbour" (2 d) is an Ammonia World. Then there's a landable moon with a thin nitrogen atmosphere, and another with a thin methane-rich atmosphere - plus other bodies with thicker atmospheres.
The farthest body of the system is a Gas Giant with Ammonia-based life.
