Frostpunk

The City serves as the last bastion of civilization in the desolate Frostland, a deep crater shielding it from the unforgiving cold that surrounds it. Here, steampunk technology thrives, providing warmth and power to its inhabitants, offering a glimmer of hope for humanity's survival amidst the harsh landscape. The city's towering structures rise against the walls of the crater, adorned with intricate metalwork and glowing steam vents as a testament to human ingenuity.
