Promethean: the Created

Aurum (Refinement of Gold; Mortality)

Prometheans who practice this Refinement seek to pass as human and to understand the human condition, and thus the soul. Some do so to become as their Lineage's demiurge creator, others to transcend the pitiful lot of that creator.
Transmutations: Deception, Mesmerism

Cuprum (Refinement of Copper; Self)

The practice of mysticism as a means of taming Torment and to gain solace (rather than enmity) with Nature. Prometheans who follow this practice tend to be the most comfortable with (and capable of) surviving in the wild.
Transmutations: Metamorphosis, Sensorium

Ferrum (Refinement of Iron; Corpus)

The Refinement of Corpus allows for the fortification of the body as a map to building a soul. Those who follow this practice are called Titans. The soul grows out of the body; he who controls the body and its the organic processes commands the soul. Prometheans apprenticed to this regimen are warriors and athletes.
Transmutations: Corporeum, Vitality

Mercurius (Refinement of Mercury; Pyros)

The Refinement of Quicksilver is perhaps the most mysterious of the five major Refinements. The Ophidians (or sometimes Serpents) seek to refine their understanding of Pyros, the Divine Fire that animates all Prometheans. Their studies take them to the heights of academia as well as to some of the most unsavory places in the World of Darkness, looking for answers to questions they cannot fully articulate. At the heart of their seeking is the simplest question: What is the Inner Fire?
Transmutations: Alchemicus, Vulcanus

Stannum (Refinement of Tin: Torment)

To be rejected by the world as a whole is as painful a feeling as any living creature will ever know. Most Prometheans, in some way or another, strive to avoid Disquiet and thus Torment. The Refinement of Tin, however, teaches that to shun Torment is to swim against the stream, to take up a fundamentally unnatural position, and thus to invite further pain.
Transmutations: Disquietism, Electrification

Rare Alchemies

The following Transmutations are not as commonly practiced as the five greater refinements.

Aes (Refinement of Bronze: Aid)

The Refinement of Aes seek to bestow succour and support to the other Created. Their work is about forging and maintaining the alliances of Prometheans and lending them aid. Their primary focus is upon the unity of the throng and the communion found therein.
Transmutations: Benefice, Corporeum

Argentum (Refinement of Silver: Mystery)

Many Prometheans turn their studies away from the world of mortals to consider, contemplate and explore the world of the supernatural around them. Taking up the role of the mad mystic, the Argentum Created look to the shadows that is cast by humanity to understand those that cast them. 
Transmutations: Sensorum, Spiritus

Centimani (Refinement of Flux)

Many Prometheans reject the notion of Humanity, instead they recognise themselves for being nothing more than monsters. Through the Refinement of Centimani, a Promethean can explore his monstrous nature.
Transmutations: Pandoran

Cobalus (Refinement of Cobalt: Impurity)

This is a rare refinement that seeks understanding through the imperfections of the Promethean existence. They are scholars and alchemists alike who seek to understand the fragile and imperfect components that make up humanity. By learning about their own imperfections a Promethean may remove them.
Transmutations: Contamination, Deception

Plumbum (Refinement of Lead: Source)

Though this Refinement doesn't reject the Great Work, it makes an assumption that most Prometheans dismiss. It says that to understand Humanity, you must first understand Prometheans. These Prometheans look to Promethean origins and history.
Transmutations: Disquietism, Saturnus

Frankenstein (The Wretched)

Shambling creatures whose limbs and organs were culled from multiple bodies. They were given life by the element of fire in the form of lightning, and they suffer from an excess of choleric humour. Their Progenitor was Dr. Victor Frankenstein's famous monster.

Bestowment: Unholy Strength
Humour: Choleric
Progenitor: Frankenstein's Monster
Demiurge: Dr. Victor Frankenstein

Galatea (The Muses)

Like their Progenitor, the Galateids were made to be loved and to love, in every sense of the word. The need for human society drives many of them. Beauty, however, doesn't necessarily predicate social graces. Many Muses find that they are unable to communicate with the humans to whom they would be so close. They make attachments easily, but they can't express how they feel.

Bestowment: Mesmerising Appearance
Humour: Sanguine
Progenitor: Galatea
Demiurge: Pygmalion

Osiris (The Nepri)

And death shall have no dominion: The progeny of Osiris know this. They came back from the dead — renewed and born without true memories, but back nonetheless — and they know that they can cheat death again. They claim to be the progeny of a god of the dead, and they expect other Prometheans to believe that and respect them for it.

Bestowment: Revivification
Humour: Phlegmatic
Progenitor: Osiris
Demiurge: Isis

Tammuz (The Golems)

Crafted from the dead and empowered through the Earth, the Tammuz take on the nature of the clay that made them what they are. They are stoic in their dealings. They are often impartial, rarely easy to move from a decision, and able to take a great deal of abuse and difficulty before they lash out.

Bestowment: Unholy Stamina
Humour: Melancholic
Progenitor: Tammuz
Demiurge: Ishtar

Ulgan (The Riven)

Thrust into the Twilight existence of spirits at another's behest, the first memory the Ulgan have is the sensation of being torn to shreds. They didn't choose to be torn to pieces. They didn't choose to awaken into agony. They didn't choose to exist, one foot in the realm of man, one foot in the realm of spirits. Each Ulgan is aware that he is without a Kut, a soul. It creates a void within him, and it is this void that is filled by the ectoplasmic non-substance of Twilight, which binds him together and forces him into proximity with the spirits.

Bestowment: Ephemeral Flesh
Humour: Ectoplasmic
Progenitor: Erlik
Demiurge: Ulgan
