A picture will probably go here in time.
Across the realm of the infinite lies the Outer Rings, the realm of the Divine Kin and the throne of the Host of Angels.
The Host made his royal decree known when he took his first breath: “I shall be known as the Host of Angels. I shall take this lawless chaos and refine it to one where law, order and logic rule supreme. I shall make my own realm, where all other forces are governed from its existence.” He forged his realm from chaos into order, the roiling expanse settled into the lands of the Outer Rings. In making this realm, the universe grew consistent. Forces would move where intended, atoms would hold together and life would be able to spring. It was his duty to ensure all would work.
He could not do so alone, and so from his image did he create the Angels. The Angels were his caretakers. They would make sure that all things that kept the universe as it is, as it is. Each a creature of reality, powerful enough to shape this world where needed, weighed down with responsibility and order.
Angels follow law but not the law of man as we know it. The law of the universe is how they shape themselves. They're bizarre creatures who look too perfect, with oddly angular features, bodies that defy our understanding of the universe. Yet each one, as alien in appearance and mind, is a deeply responsible creature. They are unburdened with freedom; a working part in the mechanism that keeps the universe stable.
Nunastrophael is a Seraphim (Angelus Seraphin) takes on two forms, one of a human guise and the other his true self.
He visually appears as a young, teenage-ish boy with dark skin. His hair is black, short and scruffy. He has four arm, of which he uses the upper pair more regularly and folds the others unless he needs them. Down his body is a vertical series of markings that look like an energy lash cracked down his body.
He wears a lilac robe, always open, and baggy leggings. His torso and chest are bare and the robe only has two sleeves for his upper arms; the other pair are folded under his robes. Along the neck the robe has a single strap, which is seamless. It also comes with a hood, which is regularly kept down.
When Nunastrophael uses Adamic Enochian, the cracks on his body glow with a platinum glow, as if the divine presence within his form wishes to make itself known. If one looks at his shadow, they may notice six wings unfurled behind him that bend at precise, yet unusual angles.
His True form is much more powerful. He is a crackling, formless humanoid form of radiant energy that is held together by only his robes. Streaks of energy flow down his body where the cracks on his skin used to be. His face is entirely gone other than eyes, which appear like the cracks on his body, and 6 wings cover his body: two his face, two his legs and two for flight. He is easily as tall as Big Ben this way.
Angels are law, given form. Their powers come from their ability to manipulate Adamic Enochian; the celestial language of the universe. Though Enochian is written, Adamic Enochian is more of a code that represents the language of the universe: fundamental forces.
Divine Form: Angels are animated by lawful, powerful energies. Their bodies are much stronger, durable and quicker than any human could ever achieve. Certain magics may also inhibit an angel's powers. Whilst in a vessel, they may retain all their powers but they are stuck with that vessel's physical limitations.
Senses unbound: Angels possess sensory awareness unbound by physical organs. Using the metaspectrum, an angel can glimpse into things that are beyond mortals.
Telekinesis: Angels are able to alter the laws of motion and kinetic energy. This functions like medium telekinesis.
True Reincarnation: An angel's death is appointed and etched into the fabric of the universe. Upon their physical form being destroyed, an angel will reconstitute itself in its Ring in the Outer Rings.
Possession: With permission, a vessel of suitable strength can host an angel. The angel supplants the vessel's will and personality with his own and controls them for the duration. Angels don't tend to let their vessels see or remember what's happening but it's entirely possible to allow it.
Shapeshifting: An angel's true form is an awe-inspiring site and gazing into its true self without a vessel or altered form can cause great physical trauma; ranging from burned-out eyes to annihilation in a cascade of holy fire. An angel can only assume its true form in the Outer Rings, Purgatory or the Netherworld, and only in their human guise on other planes of existence. Altering their form to go through realms drains a lot of energy.
Resurrection: An angel may grant a mortal reprive from death. By altering the causality of a mortal's fate, an angel can whisper the language of the universe and rewrite their death. This takes a vast toll of energy from the angel and is not used lightly. Other consequences may also come of this.
Deals: Like demons, angels have a True Name and can also make pacts and deals like a demon.
Nemesis: When a Reaper is in close proximity of an angel, the unholy core that powers their corpus reacts with the divine energies of the angel. The Reaper finds their powers supercharged, though they can't sustain this for too long as their powers will eventually begin to burn through their body.
