Praimfya Crater

The scarred world where humanity's second chance began—though the early conflict centered on Camp Jaha and the surrounding forest, not a specific crater.

Praimfya is the Trigedasleng word for 'prime fire' or nuclear fire, not the name for Earth itself—Grounders refer to their world simply as 'the ground'. In canon, 'Praimfya' is a general term for the nuclear apocalypse, not a specific crater or landing site. The early conflict between the Sky People (Skaikru) and the Grounders primarily takes place in the area around the Ark's landing site (Camp Jaha/Arkadia) and the surrounding forest, not a named 'Praimfya Crater.'

Planet Name
the Ground

Lore & Background

The landscape of the Ground is defined by its history of war and regeneration. Forests have reclaimed cities, and rivers run through ruins. The craters serve as grim reminders of the past, often avoided due to lingering radiation or used as strategic fortifications by various clans. As time passed, settlements like Polis and the Ark's landing site grew into hubs of culture and conflict.

In Their Own Story

The dust settled slowly over the clearing where the drop ship had crashed. Bellamy looked out at the horizon, where the trees met a jagged line on the sky. Beyond that lay the Crater Zone, a place where the grass turned grey and the air tasted like ash. They had come to Praimfya seeking salvation, but the ground beneath them whispered of destruction.

Reader's Guide

Praimfya's geography is a mix of reclaimed wilderness and nuclear wastelands. The climate varies by region, with some areas suffering from extreme weather patterns due to atmospheric changes. Resources are scarce in radiation zones but abundant in safe havens like the forest lands where the Ark survivors landed. Water sources must be tested for contamination before use. Culturally, the craters represent the old world's sin. Grounders avoid them as cursed ground, while Sky People view them as obstacles to colonization. Over time, some areas have become habitable again.
