AN ISLAND LOST TO TIME
Welcome to Cauldron Island. Lost to history, hiding a mystery. A vast northern chain of islands with 100km+ of railway winding its way across the craggy and desolate landscape, and the abandoned remnants of a once-thriving whaling industry there for you to discover.
Restore and activate a century-old train to travel deep along this forgotten caldera to uncover a dark secret. What you discover in the end will change how you survive in this Aurora-bathed world, forever.
