Sepiriz, leader of the Nihrain
The Nihrain, also called Nihrainians, are ten ebony-skinned brothers who serve the Cosmic Balance. Their leader is Sepiriz, the Knight in Black and Yellow. They are able to travel the Multiverse to where they are needed, but are likely native to Elric's World, in an area known as the Valley of Nihrain. They were said to have ruled their world long before the Melnibonéans arrived there.
