Known as the graveyard of Limbo, the Ossuary is where beings traditionally lay their loved ones to rest. Tombs and gravestones sprawl across its surface, tended by locals who maintain the burial grounds. Beneath the earth lies a vast network of tombs, holding countless beings and the buried secrets of their pasts.

The Foundry stretches for hundreds of miles, dominated by a massive factory built atop a sea of molten lava. Within its walls, locals toil day and night, tending machinery and producing much of Limbo's industrial goods. At the core of the factory beats the Machine Heart, its origins unknown, driving production and enforcing the relentless rhythm of the layer.

The Colliery sits at the base of a towering mountain, home to Limbo's largest repository of coal. Wooden buildings line the town's streets, leading to mines carved into the mountain's rocky base, where hidden secrets and monsters await further within.

The Sanctuary is a realm of beauty and reverence, graced by houses of worship and tranquil gardens. Its inhabitants faithfully uphold the rituals and traditions of the past, often without understanding their original meaning, as the truth that once defined them were buried long ago.

The Estuary is a swampland divided by a great river that cuts through the region, emptying into a vast body of water at the edge of Limbo. Along its banks, two rival tribes remain locked in conflict, each believing the other must answer for the sins of the past.

Crowned with towering spires and lavish architecture, the Aviary floats above the clouds. It is home to Limbo's wealthy elite, whose appearance resembles the birds of our world. Though they possess everything they could desire, it is never enough to satisfy their appetite for more.
