Dunesfolk
A feisty little bunch, with a long history of life in the desert. From an early age, they are made to drink a traditional herbal concoction to raise their resilience to poison, as nearly all the plants and animals in their native lands are venomous. There is what appears to be a thin layer covering the pupil.That too is an evolutionary response to the environment─their bodies' way of protecting the eye from the harsh rays of the sun and errant grains of sand. Unfortunately, it limits detailed ocular research to Dunesfolk cadavers.
