General History: The Payshtha was formed during the first era when the Family's came together to celebrate the coming of life and light, They all agreed that it was their responsibility to protect the world and its creatures, by any means necessary, so a board of elected fighters and hunters as well as a civilian that would represent the common folk. Every year after the new year celebrations there would be a vote to elected the next round of leaders and representatives. 
Their religion came from a mixing of all the families views and beliefs to satisfy the majority and the elders of each family teach the younger generations the history political and everyday life skills but once they came of age (10) they would be taken to be trained in a variety of combat from open warfare to grellier combat. They did have their weakness however, if it was a bad growing season or trade with the other nations dropped their economy would suffer, and being a small nation this could be devastating if prolonged, Or if they fort against a sea faring nation, though they could fight off pirates and raiders against a nation that lived by the sea they had little chance
