Dark Sun: The Scorched World of Athas
The town of Ogo is home to a prosperous tribe of about four thousand halflings. At its heart stands a massive, ruined step-pyramid that has stood for as long as the town lorekeepers have recorded. A shrine at the base of the structure houses the Spirit Oracle, a female halfling druid of unknown abilities who spends much of her time in deep communion with primal powers. Such is her reputation that even individuals from beyond the Forest Ridge seek out her far-seeing advice.
The remainder of Ogo is composed of a scattering of stone and wooden buildings amid open-air plazas. The halflings here sometimes deal with outsiders and are less likely than other clans to grab visitors and tie them up for dinner. Every year, King Urga-Zoltapl sends a levy of two hundred halfling warriors to King Hamanu in Urik in exchange for a shipment of obsidian weapons and tools. The warriors who choose to return to Ogo after their stint in Urik have a more cosmopolitan view of the world, and since this arrangement has been ongoing for the past few years, hundreds of halflings in Ogo share this experience.
