Vitaveus is governed by the Venerated Republic of Decus, itself ruled at the highest level by the Church of Decus.

The monasteries of the Decusian faith, in more modern of times, have evolved to become the learned centers of both the philosophical and medical.

The ideology behind the Church of Decus lays with the 8 virtues and their polar opposite, the 13 vices. It is by abiding by the virtues that we may aspire to ascend to a new era of existence. On the other hand, performing actions and deeds against the sacred virtues may inhibit us from achieving this goal.

There are eight virtues at the heart of Decusian faith. Together, they are known as the Sacred Eight:

• Compassion: a sense of shared suffering, most often combined with a desire to alleviate or reduce such suffering; to show special kindness to those who suffer. Thus compassion is essentially empathy, though with a more active slant in that the compassionate person will seek to actually aid those they feel compassionate for.

• Honesty: the human quality of communicating and acting truthful and with fairness, as best one is able. It is related to truth as a value.

• Honor: the evaluation of a person’s trustworthiness and social status based on that individual’s espousals and actions. Honor is deemed exactly what determines a person’s character: whether or not the person reflects honesty, respect, integrity, or fairness.

• Humility: a quality or characteristic ascribed to a person who is considered to be humble. A humble person is generally thought to be unpretentious and modest: someone who does not think that he or she is better or more important than others.

• Justice: the ideal state of humanity: a morally-correct state of things and persons.

• Sacrifice: the term used to describe the idea of selfless good deeds for others. Sacrifice is the concept of a direct relation between one’s virtues and their status within society.

• Spirituality: in a narrow sense, concerns itself with matters of the spirit. The spiritual, involving (as it may) perceived eternal verities regarding humankind’s ultimate nature, often contrasts with the temporal, with the material, or with the worldly. It is the idea in which mankind stays true to their belief in themselves and the Sacred Eight.

• Valor: also known as fortitude, is the ability to confront fear, pain, danger, uncertainty or intimidation. It can be divided into “physical courage” — in face of physical pain, hardship, and threat of death — and “moral courage” — in the face of shame, scandal, and discouragement.

These misdeeds, or vices, have long been the object of study by many of priest and clergymen. The most modern and common belief currently within the circles of the Decusian Church is that these misdeeds can be literally defined, specifically as thirteen separate ideas and beliefs that the Dae’ gain power from. Curiously enough, these commissions usually come in the form of spiritual ideas rather than physical acts, as do most of the eight virtues of the Decusian Church.

It is even believed that such deeds work to fuel the denizens of Hel (namely daemonkin) with the sustenance they so lustfully crave and require, thus enabling their presence within our realm of existence. A daemon's most important task in life is to simply manipulate and persuade those of the Mortal realm into committing these acts in order to fuel their “breed”, or similar daemonic entities that draw power from the same sort of vices and misdeeds. However, this idea goes against the “Great Doctrine”, a series of rules Decusian Faith believe to rule the universe. According to decusian lore and religious liturgies, it is said that those of both other-worldly realms, Heaven and Hell, cannot directly influence our own mortal realm due to the rules set forth within the Doctrine. The central concept is rather that of mankind's Free Will.

Representing each of the thirteen vices which empower the Dae’, a disciplined order stand as symbols of their significance and power. Each of the thirteen vices are represented by either a matriarchal and patriarchal system of rulership, or simply a “Throne”. Hence, there would be thirteen major daemons, each sitting on its throne, ruling over daemonkin that belongs to its corresponding vice. As a collective, the thirteen thrones are referred to as “The Pantheon of the Thirteen”.

• Falsehood: the telling of untruths, unfaithful actions and deeds.

• Hatred : feelings of intense dislike, anger, hostility, or animosity, and the acts committed from them.

• Cowardice: lack of courage, or behaviors that shows such a lack; a father leaving his son to die out of lack of courage is a prime example of this vice.

• Enlightenment: the enlightening of somebody or a cause through the means of dark pacts with the throne bearer of this vice itself, i.e. the signing of one’s soul for monetary or other gains.

• Sacrilege: the disrespectful or irreverent treatment of something others consider worthy of respect or reverence, i.e. the defacement of a holy symbol by a follower of its faith.

• Covetous: having a strong desire to possess something that belongs to somebody else, and deeds committed out of this desire.

• Shame: negative emotions that combine feelings of dishonor, unworthiness, and embarrassment.

• Pride: haughty attitudes and actions shown by those who believe, often unjustifiably, that they are better than others.

• Murder: the committing of murder, tried and true.

• Chaos: a peculiar vice, one whose deeds are more often than not dictated by the throne bearer itself.

• Wrath: the vengeance, punishment, or destruction wreaked by somebody in anger, and the fury often marked by a desire for vengeance which causes such other deeds to be committed.

• Lust: the strong physical desire to have relation with somebody, without associated feelings of love or affection, i.e. the conductance of adultery or forced acts.

• Hubris: inordinate pride in oneself or one's achievements above the Eight virtues, Decus, and creation.
