The Tumeroks call their home world Ezheret-Hazahtu, although they only live on the body they call Ezheret. This requires some explanation. While a sun does rise and fall in the sky, Ezheret actually orbits another, larger planet called Hazahtu. Hazahtu, or “The Blind Eye,” is an enormous, cloud-shrouded grey-blue orb. Legend holds that when the eye of Hazahtu loses its occlusion, the Tumeroks will be judged for their stewardship of the world.
Ezheret is hot, humid, and prone to extended periods of foul weather. Gales and hurricanes are frequent, perhaps due to the unusual sparseness of dry land. The Tumerok tribes are spread across myriad archipelagos, separated by hours or days of journey by boat. This partly explains why drumming is so predominant in their culture; since it is difficult to stay in direct daily contact, friends and relations will stand on shores across from each other and pound their drums to communicate across the water. This “drum talking” is also used to stay in contact while riding out inclement weather.
Ezheret is a moon world capable of supporting several species. Three of these species appear to have better than animal intelligence, capable of crafting rudimentary tools and sustaining a limited form of speech in the lesser of these forms to the ability to speak in a tongue in the greater. The Tonk or Tumeroks share Ezheret with the scavenger Drudges, as well as the perpetually warring Banderlings and Mosswarts.
