In the early days of Greece, there was no such thing as "random". The outcomes of things were predictable, and always the same. The Greeks soon became tired of this entirely predictable life, where were the fun parts of life to be found when everything was always predictable and the same?
The people of Greece wanted things to change, they wanted things to be random. No longer did they want everything to be so predictable and boring, no, they wanted things to be random. They wanted life to be exciting and unpredictable.
How would the people of Greece accomplish this though? How would they suddenly allow things to be random? They needed intervention from a God, no other being could create such a phenomenon like randomness.
They needed to make a deal with the Gods, a deal to allow randomness to exist. They had questions such as "Which God should we ask?" and "Are we asking for too much?". One God they must ask was Athena, for total randomness without order leads to chaos.
They thought that they'd also need to ask Janus, the God of choices and doorways, to provide one of the key elements of chance and luck, the many choices, or outcomes, of a scenario. How were they to bring these Gods together to create randomness and luck though?
The child, a combination, of both Athena and Janus, could create a being, a God, with the ability to create randomness, or chance. This could be the answer, the solution to the boring, predictable life, that the people of Greece wanted. How could they convince the Gods though? How could they get them to create a God with the ability of chance, the ability of random?
