The Great Mystery

The Great Mystery is the conundrum on what was life like Before Land.
Most Human cultures are aware that life Before Land involved a sea-nomadic life for humanity. When the sea became too dangerous and there was no more material to repair ships, most humans returned to live on land, hence the era of After Land.
Exactly why humans decided to live on boats, and for how long, is a mystery. However it is certain that humanity had lived on land before they fled. Many human ruins can be found scattered across Gaia. Well preserved ruins can be found on the continent of Sanguin, however few researchers dare to go due to the risk of disease and other monstrous dangers.

Players of the visual novel may be able to explore The Great Mystery through some character archs later in the game. The character Jordan will be especially connected to this line of story.
