Oscuri

History
The Oscuri first surfaced in Japan, believed to have been hybrids of two ancient (one now extinct) species of demon. The first were believed to have existed at around 2000 BCE. The first Oscuri believed humans to be insuperior beings, the most ruthless even feeding upon said humans. Oscuri generally avoided associating with other species of demons, regardless, gaining large numbers quickly once their presence became known.

Interbreeding with humans was initially quite rare due to the Oscuri's nature, though this would become more common leading up to and after the formation of the Atali Tribe.

This brought about beliefs about tradition amongst the species, as well as the risks of complications in childbirth, and in particular, corrupt, out of control hybrids. The Oscuri fought in their own civil war, the Atali Tribe ending up as the victors of the battle. The remaining Oscuri against the Atali Tribe went into hiding, and have not been seen since.

The Atali - Orisan war later broke out, the Oscuri's numbers declining further until the eventual collapse of the tribe after the war.

Most remaining Oscuri would later unite again under the Moisson Clan, albeit almost all hybrids, unlike the Atali Tribe where pureblooded Oscuri were much more common. Oscuri descendants are also known to be in the Kujisaki Clan, and also (formerly) in the Collett Clan.

Traits
Many of these features (excluding skin tone) can be found in hybridised Oscuri as well, though some are rarer than others.
 * Purple/Violet/Pink Eyes - Typically, Oscuri had glowing purple/pink and/or violet eyes.
 * Other Purple/Violet/Pink Features - This typically included the spine, ribs and the tip of the tail.
 * Smoky Black Skin - Oscuri had very dark skin, which helped them blend into shadowy areas.
 * Horns - Most, though not all Oscuri had two, small to medium sized horns on their heads. Those 'higher up' in the hierarchy had larger horns.
 * Tails - Most Oscuri had long tails, with blade-shaped tips.
 * Black or Dark Silver Hair - Oscuri had black hair, which was usually grown down to at least shoulder-length.
 * Longevity and Fertility - Pureblooded Oscuri were almost immortal, however due to circumstances of war and their small numbers, lives were often cut short.

Abilities

 * Dark Magic - The Oscuri specialised in the arts of Dark Magic, being very talented sorcerers.
 * Destruction - Some Oscuri can use the essence of Destruction, however this is rare. This may originate from one of the demon species predating the Oscuri.
 * Soul Magic - Oscuri are able to use Soul Magic, to a limited degree.
