[quote=@The World] It depends on the organ. For example, overall EE generation and output are affected by them, and certain techniques can only be used if you have certain ones. As for the number, having one means you can't use any of the techniques I just referenced since they each require a combination, and having more than five can result in conflicting functions and blockages, since there's only so much room in the body. As for how they're formed, they grow from residual EE in a parent during a person's fetal development, unless they're from a universe without EE, in which case they're formed alongside the EE pathways when entering a universe with it. [/quote] Suzy: Then the formation of mine are probably from the second case. Is there a way to artificially grow them from exposure to someone else's EE? And are those techniques you mentioned the things you taught me?
