Starfield:Armillary

The Armillary (ahr-muh-ler-ee) is a device made by bringing multiple artifacts together. A completed Armillary is desired by many Starborn, as it grants access to the Unity. The Armillary itself is described as being "in many ways... a model of the multiverse itself". By completing the Armillary and assembling it into a grav drive aboard your ship, you can use your grav drive to take you to the Unity, the center of the Multiverse.
