According to Briéron tradition, the world was once divided between humans and the korrigans/ kourikans (Breton fairies or goblins). Humans and these supernatural beings shared the upper and lower worlds, but humans eventually trapped the korrigans underground by sealing their entrances.
Since then, the korrigans have tried to raise the land of Brière to recover their lost world. The rising marsh was explained as their attempt to return to the surface.
