The first life of our protagonist. An immortal cultivator who has lived hundreds of millennia. He is the Head Librarian and Formations master of a famous Sect.
A formation is a magical circuit comprised of runes and characters, utilising qi, to achieve an effect. In some ways they work similar to electrical circuits of our world.
Qi is the energy of heaven and earth that cultivators utilise in all aspects of their lives. The relative density of natural qi is variable depending on what tier of realm one is in.
