Seven elements

In Shidinn occultism, Seven elements is a classical element theory as an extension to, and moving beyond, Hellenistic concept of four elements and Chinese wǔxíng. The elements are Fire, Wood, Light, Earth, Air, Water and Void.

It is not related to another sevenfold conceptual system of Genshin Impact.

The elements

Unlike in wǔxíng, overcoming (相克 xiāngkè) is the dominant interaction between elements. Each element overcome three elements and is overcome by another three.

Ternary relations

The translation may be changed later.

Three elements overcome by one another element are confronting (同仇). Three elements overcoming one another element are accusing (同食, literally ‘same food’). For example: Wood, Light and Air are confronting since each of them is overcomed by Fire (the relation may be called Fire-confronting). Fire, Light and Earth are accusing since each of them overcomes Air (the relation may be called Air-accusing). Note that the ternary relations cannot be used as binary relation, for example, Fire, Wood and Earth are confronting, but we cannot say that Fire and Wood are confronting.

For any two elements there is a unique element to be confronting, and a unique element to be accusing along with them (the two chosen elements are different). For example, for Wood and Air only Light is joint to be (Fire-)confronting and only Earth to be (Water-)accusing.

If seven elements are seen as points and seven confrontation or accusation triads are seen as ‘lines’, the whole system will form a Fano plane (finite projective plane of order two). The projective plane is the smallest non-trivial projective plane.
