Sanhul Arm

The Sanhul Arm is the southern Galactic Arm of the Andromeda Galaxy. Many Andromedan civilisations reside in this region, as many of the planets are life-supporting. There are many stars in the Sanhul Arm that have a medium- to high-metallicity content, unlike the Arm's northern counterpart, the Gasruk Arm.



Dirpion Nebula
The Dirpion Nebula is the most well-known area within the Sanhul Arm. It is composed of many stars. The Dirpion Nebula's components originated from the star Dirpion-104, a hypergiant which ejected much of its mass into space before going hypernova 3 billion years ago.
