Energons are the energy produces by the brain that make psychic abilities possible.
Because energons are carried in the same channels as "sexual energy" they must be kept completely open and clear to allow the the energy to traverse them. If a telepaths channels are not completely clear this can cause an overflow and cause great harm or death.
During threshold sickness, usually during puberty, when a telepaths laran starts to awaken precautions must be taken or death can occur from the channels being overloaded. Keepers and female matrix workers must also monitor their channels in order to keep them clear or risk harm.
