Updates will be made in this chapter to keep up with the story. I don't want to give spoilers, so here is an overview of the basic things.
PRANA—-- The basic energy of the world. Found everywhere, in every thing. But it has a special purpose in every other thing.
CHAKRA —- A special conjunctions of Nadis which gives access to certain powers.
NADI—--- Vein-like structure in beings that is both physical and metaphysical in nature. Prana flows and is stored in this.
Five Primordial elements are as follows : Earth, Water, Fire, Air and Space. The first five chakras in humans represent these elements, from the pelvis up.
Primordial Paths—- The paths that have generated every other path present in this world. Further explanations are in the story itself.
Voidhearts—-- Mysterious beings? Figure out what they are through story.
I think that's it for now.
