Magic

Magic in the Desideria, is a fundamental part of life. Generally used to describe a whole set of phenomenon, there are several forms of magic which are best documented and understood.

Atavisms
Atavisms are physical changes or manifestations to the casters body, whether transient or permanent. In many cases, it may be used to make the caster more beastlike, but is certainly not the only method seen. Shapeshifters are the most common form of Atavism, and Silkies are thought to be using Atavisms when they take on the form of animals.

Utterances
Utterances are ritualistic spells cast by speaking specific words, generating a specific change or effect in the world. In general Utterances tend to have less direct effects, and there won't always be a direct connection between the effect and the caster. That said, there are a range of quite obvious effects, including the raising of the dead or changing the weather.

Utterances are thought of as changing the rules by which the world works.

Manifestations
Manifestations are direct creations from the souls and minds of the caster. They require nothing but force of will, and manipulations of their inner fire. This will often come in the form of creating magical implements such as arrows or tools, to generating pure energy in the form of a fireball.

Transmutations
Transmutations are the physical changes to world around the caster. The most classical examples of this involve turning one element into another, but can also appear as more subtle changes such as calling down lightning during a thunder storm.

Affinities
Affinities are best described as modifications of the soul, or the inner fire. These forms of magic do not have an obvious effect outside of the way the caster behaves. Common examples are having premonitions, being able to see spirits, and having visions of the past.

Rites
Rites are a range of types of magic all united by the requirement for preparation. Rites will require ingredients and ritual to be cast, but often have very significant and far reaching effects.
