Much like its Squid-related modern interpretation , Gil Game represents life and struggle of the individual as an evolving acceptance of the human experience, throughout the eons of history. Chaotically navigated and sometimes colorfully narrated, by the communicators of our speices.
Gils are roughly twice as efficient in hydro-ventilating oxygen and carbon dioxide, than lungs of mammals. A minor genetic mutation - single nucleotide polymorphisms - in the embryo of large aquatic mammals, have shown* to trigger the development of actual functioning gils in place of lung tissue.
Ancient Egyptians used ceremonial golden amulets with eye-shaped inserts in place of the gils, representing far-seeing both into historical- and future times. An important magical artifact granting the priesthood abilities comparable to what we enjoy today through modern-day smart phones.
"Gil game is not for everyone. We play the game today using technology in place of magic, although the game itself remains as ancient as it is unforgiving. You have been warned."
