Located at the intersection of the Angustia region and the desolate Outer/Norma arm rest the Angustia Trinity, a system with three O-class giant stars and an O-Main Sequence star [O9 IIIA, O9 IIIA, O7 VA, and O0 VZ]. The O9 IIIA stars are the largest designation for an O-class star. While a system with three O-giants is rare even near the core, a high mass system such as this located in the Outer Arm is incredibly rare. Furthermore, the system is equidistant from Colonia and Sol, marking an equilateral triangle between inhabited space - lending its lore as the Angustia Trinity.

Approaching Angustia Trinity requires a deep descent into the bottom of the outer edges of the Milky Way. There are few stars around here, only the occasional A-class illuminating the celestial sky. As such, Angustia Trinity can be seen from thousands of light years away. The view is majestic, as the path to Angustia Trinity aligns with the Andromeda galaxy, the Triangulum galaxy, and the Magellanic clouds. Explorers be weary, however, as plotting a course to this system without the aid of a Fleet Carrier can be arduous, as the path is often convoluted because of the sparsity of systems in this area.

Immediately adjacent to Angustia Trinity is Fraufooe GR-w d1-1, a system with four water worlds [3 of which are terraformable].
