Onmyōdō, or “The Way of Yin and Yang” is the magic of Sekai. Based on philosophies of Five Elements and Yin and Yang, it is a way for humans to interact with the spirit world. It’s practitioners are known as Onmyōji.

The basis of Onmyodo comes from the five elements of nature – called the Godai – Earth, Wind, Water, Fire, and Void. These elements describe the connections between varous fundamental essences of existence. Each is representative of an outlook on life or a style of doing things, and not as much the classical elements themselves. Each element governs two schools of magic – called the “Arcana”. In these pairings, one arcanum represents the Yin of the element – the subtle, shadowy, and feminine – while the other represents the Yang – vibrant, bright, and masculine.

To become an Onmyoji, a character most make it a part of their High Concept aspect, and spend one refresh on the stunt “Onmyodo”. You then may choose an element .You gain access to casting spells from that element, and you can cast spells from other elements at the cost of 2 mental stress. This element is your “Governing Element” – and it should be so in your role playing as well. Finally, you may now purchase ranks in the Onmyodo arcanums, explained below.

The Arcane Ladder

For magic, it’s difficult to say what should constitute a “mediocre”, “fair”, or “legendary” spell. Hence, we have the arcane ladder, ranking the difficulty of spells according to the sort of effect they might produce. Simply add together the factors of the spell in each column to determine the difficulty for casting. The consensus of the group comes first. This is only a guideline.

This table is only for static targets, so Attack, Defend, and Recover will be addressed seperately. Generally, this table will be used for Overcome or Create an Advantage.

Divinations provide sensory perceptions or knowledge about sumthing under an arcanum’s domain. Commands involve pressing an existing being or phenomenon to do your will. Alterations change the essence of a target. Abjurations protect something within or from an arcanum’s domain. Destructions remove obstacles. Creations summon things that are not present, either by creating them or calling them from afar.

Complexity is a subjective matter. Creating a solid block of iron would be fairly simple. Creating a Katana would be complex. Changing a Hunger Kami to a Thirst Kami would be simple. Changing a Hunger Kami to a Rock Kami would be complex. Warding a room against all human beings would be simple, warding against all human beings from Kagoshima named Tetsuya would be complex. And so on.

Connection is a measure of the caster’s metaphysical distance from the target. Normally, the caster needs to at least be able to see a target in order to cast a spell. However, mages who master Sympathetic Magic (a stunt) can cast spells on targets they cannot see by holding a part of the target (a lock of hair, a branch of a tree) or personal item owned by the target. Casting by knowledge alone is more difficult, but not impossible. Of course, a failure could mean the spell targets someone or something entirely different.

Practice Targets Size Connection (* with stunt only) Complexity Duration
+0 Divination self cat touch (same zone) simple scene
+1 Abjuration 1 target human sight (nearby zone) session
+2 Destruction room full car personal item* story
+3 Command building full house intimate knowledge* moderate permanent
+4 Alteration town full airplane second-hand knowledge*
+5 Creation whole world building complex

Ofuda is a small charm that can be hung in a home (or an amulet called an Omamori which offers personal protection) that aids in warding an protection. Using one in an Abjuration reduces the difficulty by one.


Maho-Tsukai are Onmyoji who learned a secret art of Blood Magic – an art originally taught by Oni. Part of this technique involves permanently etching a tattoo on ones skin. The ink is made with liquefied taint itself – effectively permanently tainting the Onmyoji. Once this is done, however, the caster can empower their spells by using their own blood. It is said there are powerful Maho-Tuskai who can even us the blood of others to power foul rituals. To become a Maho-Tuskai, one must take an aspect declaring so. They then must spend 1 refresh to take the stunt Blood Magic. Additionally, they gain one rank of Taint.

Below are some sample spells. These are not by any means meant to be comprehensive – just an idea. You are free to create your own spells with the guidelines above.


Earth represents our connection to this realm, to living things and the matter that surrounds them. Onmyoji with a connection to the earth tend toward stubbroness, traditional thinking, and a focus on the collective good. They are conservative in their views, resistant to change. They also tend to be the most physical of casters, mixing their own skills in athletics or martial arts into their rituals.

The stone, resolute, remains calm and unperturbed in rushing waters.

Water is the element of endless, flowing change. Of things without form or substance. Take it once in your hand, and it is gone in an instant, but its power can raze cities or foster future life. Mentally, it is the acceptance of life’s constant changes, a oneness with the flow of things. Onmyoji of water are adaptable, rarely surprised by the vicissitudes of life, but frightfully powerful when roused to anger. They are rarely found in leadership positions, but take readily to working with others.

The leaf floats softly on rushing river waters as bough and branch snap.

Fire governs the dynamic, the forceful. It is the sudden outburst that rends asunder and the pounding heat that drives men mad. It is passion, drive, desire, and firmness of intention. The Onmyoji of fire are readily known by the intensity of their gaze and the zeal in their words. They are born leaders, rarely content to do as others have done, charging headlong into the fires of hell without thought of peril.

Flames of men’s passions, burning for but a moment. Ah, but how brightly!

Wind is the element of freedom, chance, chaos, and the unseen spirits that bring the ripple across still waters. An Onmyoji of wind shows independence and care-free thinking, prone to flights of fancy and moments of divine inspiration. Revolutionaries, poets, wanderers, and merrymakers find their paths lead towards the wind. Yet there is also a benevolence and patience to the breeze that blows even the heat of summer, cooling hotter heads and uplifting spirits.

Gentle summer breeze makes ripples across a pond, whispers things to come

Void is the prepresentation of those things beyond our experience, the unknowable Other. It is the realm invisible, the Great Beyond. THose who wish to truly know the secrets of creation, to peer beyond this life and into the next, are drawn to the path of Void. Most onmyoji of the void are unfulfilled by normal, mundane life, and seek ever higher understanding through adventures or asceticism.
