Site 1: Promise is the site of the first Andromeda Initiative outpost on Eos. The site was chosen for its proximity to a water source, but it was soon discovered that the water required non-standard decontamination to become usable. The site was initially abandoned by the Initiative when the planet was found to be too difficult to survive on due to both natural and unnatural threats. A second attempt to create an outpost by the Initiative is named Site 2: Resilience. Site 1 is also the landing site of Pathfinder Ryder's first mission to gain a foothold on Eos for the Initiative.
Even after the radiation issue is dealt with and Prodromos settled, and despite its buildings being intact, Promise remains virtually abandoned.
The site consists of U-shaped cluster of small structures surrounding a small water feature and a power relay station to the southeast on a ridge. The village is surrounded by barriers that help to keep out the hostile environmental radiation caused by the remnant structure until Ryder is able to shut it's operation down. To the far west is a large ring-ed structure designed to generate drinking water. Some of the doors a sealed shut until Ryder restores power to the site during the mission A Better Beginning.
A research center is located in the small northeastern building besides the Nomad crate, here weapons and modifications can be developed or researched as on board the Tempest.
Promise's sole known resident is Clancy Arquist, first encountered during A Better Beginning. He remains in Promise as a merchant, although he is not identified on the map as such.
