Space. It was something that everyone was able to know without actually knowing. Without understanding, everyone influenced space and space influenced them. The space that their bodies and souls occupied was a true fact of the world. A reason that they existed and a reason that they could influence other things in space.
While the space they occupied was not unique to them, it was something that everyone was able to be part of. Many had wished they could understand why they were and what they were. But not many had been able to directly understand what space was.
There were many theories that came and went that had been written and lost over time. Many researchers that had no affinity or had a great affinity to space had been influenced by their studies of space. Some had even discovered space mana to exist but been unable to understand it.
