Unistorms

The Unis and White Markings Unis are not affected by white markings in the same way that horse breeds are. No markings cause anything such as forced blue eyes; instead, both eyes on the affected horse turn heterochromatic. There is only ever sectoral or central heterochromia. Complete heterochromia is not caused by white markings. This means that a Unis would not have one silver eye and one blue eye - it means that each eye would contain both silver and blue, although the amounts of each will vary from Unis to Unis. The Unis does also not suffer from lethal white syndrome. Instead, any Unis that would be an embryonic lethal is instead steril
