1st Layer

Overview:
The first Layer within Reborn: Apocalypse serves as a tutorial for all newly transported individuals of each species. Each species introduced into the layers have their own first layer, which is uniquely suited for their race.

Currently only the first layer for humans has been widely expanded on, knowledge on other first layers is vague.

Basic Knowledge:
The first layer for humanity is reached simply by being transported into the  'game' of the layers. Waves of approximately 1 billion are transported into the first layer at a time. Within the first layer the time rate is different to that on Earth, a day on Earth is much longer in the first layer.

Geography:
The First layer of humanity parralels what can be found on Earth, in the fact that the layer is made of sprawling sky scrapers.
