What aspect is tied to having the desire to know all there is to know? I for example need answers to everything and when there isn't one yet, I get really upset. It drives me mad. Eg, I don't care what ghosts are, if they're dead people, energies, hallucinations, I don't care! I just NEED to know. I appreciate theories, I like reading then but they don't satisfy me. They are not the absolute truth. We know how exactly lightning works. I want, need, to know how all the unexplained things work
Light? Likely. Maybe Void, since you seem to want to see through all those mysteries and the unknown.
