The first time you walk all the way to the shore, Byron makes a comment about the saying “the sea will claim everything”. This is a reference to the game The Sea Will Claim Everything, designed and written by Jonas and Verena Kyratzes.

There’s an old saying about how in the end, the sea will claim everything. I have no doubt that this is true: in the long history of the human species, entire regions have disappeared under the waves. Places like Beringia and Doggerland still echo in our cultural memories. But we shouldn’t forget that life began in the sea; we are the children of the sea, and it’s not through floods and ruin that the sea will claim everything, but through us.


At the east, north and northwest limits of the island there are three fans that will propel you to different points of interest near the central, mountainous area. Next to the east fan there is a wooden bench (painted pink in patch 1.05), and there are two rubber ducks in the northeast shore. Unlike other areas these are physical objects, not anomalies.

There is a probably misnamed terminals: rather than the expected THIRIEL_EXT-2, it is named just TERMINAL.

This is the only main area where no ancient human artifacts can be found.

Conversation with the expedition crew

You can speak on arrival with Alcatraz, Yaqut, Melville and Byron. There’s a scripted encounter with Melville after solving Dual Stream. An additional line of dialogue opens up with Alcatraz after finding Our duty.
