Features[]

Sign of the Cinder Isles
The Cinder Isles are positioned downstream of the River Lowlands and can be accessed from this region. Its defining features are its two islands. One of the islands contains the Island Tower, which has a room that connects to the simulation built by inhabitants of the Stranger.

The burned temple
On the other island is a burned temple that used to be dedicated to the Eye of the Universe. The metal symbol of the Eye can still be found inside the temple.
A slide reel theater is built along the cliffside, where two slide reels can be found. The first slide reel shows how the Stranger's inhabitants analyzed the Eye of the Universe, while the other slide reel reveals how the inhabitants used seals to lock up the Prisoner.

Slide Burning Room[]
The Cinder Isles contain a Slide Burning Room that is usually hard to find. A map in the Abandoned Temple shows the location of the room. It is located behind the slide reel theater, in a hidden bay. The room has a slide reel that reveals how to access the Forbidden Archive in the Starlit Cove. It also has a passage that connects to the slide reel theater.

Dam[]

The flooded Cinder Isles
The Stranger's sails activate around seven minutes into the loop to move the spacecraft away from the impending supernova. Due to the strain this puts on the Stranger, the dam starts breaking down. 13 minutes into the loop, the dam eventually bursts. The Cinder Isles are hit 30 seconds later. The buildings on stilts are destroyed, but the two islands are high enough not to get flooded. The Island Tower falls down 20.5 minutes into the loop, severing its connection to the simulation.
History[]

Inhabitants burning the Eye temple
The Cinder Isles originally contained only residential buildings, the slide reel theater, and a temple dedicated to the Eye of the Universe. It was also where the Prisoner seems to have lived. When the Stranger's inhabitants first arrived at the Eye of the Universe, they analyzed the Eye and found out that interacting with it would lead to the end of the universe. Horrified by this discovery, the inhabitants burned the Eye temple on the Cinder Isles.

Inhabitants entering the Island Tower
Shortly after moving the Stranger near the center of the Solar System, the inhabitants started constructing a simulation modeled after their home moon. On the Cinder Isles, they built the Island Tower where they went to sleep to connect to the simulation.

Slide reels being burned
After the other inhabitants locked up the Prisoner, they used the Slide Burning Room to upload a portion of the slide reels into the simulation. Most of the reels were burned there afterwards, with the exception of a few of them, which only had specific slides burned. Lastly, the portrait of the Prisoner in their house was scratched out. The Cinder Isles were then abandoned as the Stranger's inhabitants went to sleep in the simulation forever.
