Cornelian horse (Eufez)

The Cornelian horse is a species of wild horse native to the region and the feral ancestor of Cornelia's tamed horses. Their coloration ranges from brown to dark grey, and their manes are typically long and curly. A common myth among locals is that these horses are descended from unicorns. Today, the horses are low in number as many have perished from a disease which can be dubbed only as "mad horse disease". There have been many cases of these "crazy horses" charging blindly into villages in search of food, causing damage to buildings and occasionally injuring people. The horses suffering from this disease have been studied, as their behaviour is similar to those experienced by people who have eaten psiloleaves. Since these horses so often graze in fields where these plants are common, it has been speculated that constant consumption has resulted in some genetic deformities among offspring. This has essentially led to an offshoot of Cornelian horses which bear these mad traits. In humans, psiloleaves are often associated with psychedelic experiences.

The Cornelian horse also appears in certain plains in Pravoka.
