Traditions about Usal and the Zugubals are based on the story of Thoegay, a fiercewarrior, Zogo Le, and skilled navigator who commanded a ship crew of thirteen: a firstmate named Kang and a crew of twelve men, called the Zugubals. The group embarkedon a long expedition at sea on a hot day. Before long, the crew began consuming theirrations in zest. They were warned by Kang to conserve their supplies, but before longthey had consumed the water for the entire trip, including Thoegay’s. When Thoegayrealised this, he flew into a fit of rage and killed the 12 men. Because the Zugubals werealso spiritual beings, they could not die, so Thoegay cast them into the sky as two groupsof six stars: Usal (the six brightest stars of the Pleiades) and Utimal (the six brightest starsof Orion’s belt and scabbard). Thoegay then ascended into the opposite side of the sky,taking Kang and his canoe with him. He can be seen as a large constellation holding aspear in his left hand (the Southern Cross) and a Eugenia fruit in his right hand (theconstellation Corvus), standing at the bow of his celestial canoe (Scorpius) with Kang(Antares; Alpha Scorpii) sitting at the stern (Robinson 2016a).

In its purest sense, game theory is the study of models of conflict or co-operation between intelligent decision-makers. Everything from the functioning of ant colonies to which products consumers might buy has been explained with this mathematical framework.
