A group of halflings known as the Pesperes lived in a small community in Lyrilla away from the other halflings. These halflings had incredible luck that allowed extraordinary things to happen to them. And then, one day, it ran out. A lunarian ship crashed into their community and the destruction wiped out most of the Pesperes and the lunarians. Those that survived turned to the Gambler Divine for salvation and were transformed into a new species.

Pesperians live in the same community, avoiding the msawhat-infested ruins of what they call Pesperis Home or Pesperia. They now call their nation Urisia, which means "Vestige of Fortune."

The pesperians have small communities centered on the number seven, which rules their lives. All councils, companies, even families must have things, people, positions, and more in multiples of seven (exponents of are better, or just seven). These small farming communities are structured such that they are led by small councils of elected leaders. The communities are tight-knit and take care of one another, preparing for the bad times when they can. People are well attuned to their luck cycles and remain aloof or even take a leave during their times of low fortune.

Childen are cared for collectively, but with a primary caretaking being their immediate and close extended families. No more than seven generations will live in the same household, and never just six. Schools are run but not essential parts of the community--families educate the young more often than not. Trades and crafts are passed down through families. Trading with other communities is common.
