Acadia

This abandoned observatory turned synth refuge is located on the top of the mountain. The immediate area around the observatory is relatively safe and pleasant, due to the absence of the Fog. This place has significant ties with several quests. The observatory has three floors and several containers with basic loot and components.

First Floor

This is the main floor where you can find DiMA and his machines, as well as Faraday's office. In the end of the circular ledge, you can find the Storage Room key.

Basement 1

This is the common area for the synth refugees. You can find weapons and armor workbenches here. Dejen is the shopkeeper. He sells Old Reliable, a unique lever-action rifle and Sergeant Ash, a unique flamer. Cog is another merchant iand he sells a unique recon marine chestpiece.

An issue of Islander’s Almanac on the counter near the armor workbench.

Aster is Acadia’s doctor who also gives you an unmarked quest of bringing Aster flowers to her in exchange for caps.

Basement 2

This is where you can find Kasumi and the other synth refugees. There's a master-locked terminal and door in the small office beside the Storage Room.
