Way back when on the island of Gaia, people settled disputes with clubs. Then Shama, who lived in the west of Gaia, discovered he could make tools with flint. He even discovered that he could put a flint tip on a heavy stick and throw it at somebody attacking him with a club. He began making more and more spears to protect himself from those with clubs.
Shama's stockpile of spears frightened Putmed who lived in the north of Gaia. Putmed began stockpiling spears to defend himself against Shama. This frightened Shama even more and he began stockpiling even more spears.
But Maowen who lived in the east of Gaia was also frightened by these two stockpiles. Maowen was loosely allied with Putmed, but he didn't fully trust Putmed to protect his interests. He too began stockpiling spears. He never stockpiled as many as Shama or Putmed, but they made him less insecure about an attack by either.
Shama, Putmed, and Maowen realized their own stockpiles were a threat to themselves and reached an understanding to not attack each other with clubs or spears.
Kog lived on a tiny peninsula of Gaia and he was frightened by all three of his co-islanders' stockpiles. Although he had some of the same ideas as Putmed and Maowen, he couldn't be sure they would support him against Shama. He decided he should start making his own spears. None of his spears worked very well; he couldn't aim them very well and the flints often came off in flight. Nonetheless, Kog was very unpredictable and Shama, Putmed, and Maowen couldn't be sure that he might throw spears at them.
Shama, Putmed, and Maowen told Kog that he shouldn't have any spears, but the more they told him this, the more he wanted to have spears.
The historical record is incomplete as to what happened next, but Gaia is devoid of human habitation. Archeologists have uncovered many skeletons in all parts of Gaia with spears through the bodies.
