Saklas

Saklas is the Shard created by Samael who acted as the leader of the Grigori in the Great War as his representative. Following their capture, they were cursed by Gabriel into a Fallen Angel/Dragon hybrid before being sealed into the Cocytus.

In Chapter XXX, it was revealed that they were the true alter ego of Yaldabaoth, the leader of the Outer Gods.

Appearance
Saklas was a tall and beautiful person with shoulder-length champagne-golden hair and amethyst-colored eyes. Their hair was styled in an updo with an ornate golden crown, which depicted a dagger piercing a heart.

They wore a long indigo-colored robe which dragged on the floor and had high-slits in the sleeves, the inner fabric was red with a regal pattern, and an intricate golden design of the forbidden apple was also embroidered on the right shoulder of the robe.

Beneath the slits of their sleeves, they wore a tigher black long-sleeved garment, with the sleeves forming a pointed shape on the back of their hand and tied around their middle fingers. They also wore tight black pants beneath their robe, as well as high-heeled black boots with golden linings.

Cursed Form
After they were cursed and imprisoned in the Cocytus, Saklas transformed into a large and ominous creature with bizzare features.

The upper part of their body is like that of a masked androgynous person with fangs in their mouth and giant black-feathered wings, while their lower body was like that of an Eastern Dragon, with gleaming obsidian scales and multiple serpents growing from their waist.

When they were first summoned by the Hero Faction, they were crucified on a large cross with holy nails driven into various parts of their body (arms, tails, wings, etc.), as well as several other restraints that had ancient Enochian hieroglyphs written on them. Their eyes were also covered with a blindfold that had tears of poisonous blood dripping from underneath it.

Personality
Due to the multiple layers of seals placed on Saklas, they are unable to display their personality. Issei mentioned that he sensed various types of negative emotions such as pain, jealousy, suffering, and resentment from them. After they were broken out by Yaldabaoth, their true persona began to rise to the surface.

They possessed a twisted and sadistic sense of humor and found entertainment in the suffering of others, both allies and enemies alike. They had also shown to be quite snarky, often answering people's question with a fair amount of bitter sarcasm.

They had demonstrated an immense loyalty toward their origins Samael to the point where it resembled obsession. Kokabiel described them as being Samael's greatest fanatic, and would gladly do everything and anything the Archangel asked of them regardless of how impossible or morally wrong these orders were, as well as disregarding the possibility they might die trying to perform them.

They possessed a massive hatred toward all snakes and Dragons, even before their imprisonment. However, they did show to have some begrudged respect toward the Dragon Gods, though Kokabiel stated that this was only because of their status as Samael's bastard children.

History
Saklas was a Shard created by Samael shortly before his defeat and subsequent imprisonment as his representative, leading the Fallen Angels and the Grigori as the Governor-Consort.

Under their reign, the Grigori went under major changes, which were noticeable by all other factions and pantheons. From a group of Fallen Angels that served as a shelter for exiled Angels and the teachers of humanity, they became a military organization greatly-feared throughout the moonlit world. They invaded the territories of numerous mythological factions and expanded the Grigori's territory into an empire only seconded by their heavenly brethren.

Sometimes in the first-century AD, under the instructions of Samael through one of their dreams, they performed an ancient ritual to split parts of their consciousness and powers into an empty vessel, which they named Yaldaboath.

In the Great War, alongside other Governors and Cadres, Saklas led the Grigori and the Fallen Angels into the battlefield to fight against the Angels and the Devils. However, they were eventually captured by Gabriel's personal legion and brought toward the Archangel.

There, she transformed them into a Fallen Angel/Dragon hybrid and cursed them with an immense poison that could virtually kill any snakes and Dragons. She then threw them into the deepest depth of the underworld and sealed them within a barrier of frozen water of the Cocytus. Onto them, thousands of ancient Enochian seals and hieroglyphs were placed to ensure they wouldn't be able to escape.
