Jealousy of the Spirit Realms

Jealousy, when in the context of the Spirit Realms, refers to the influence the Spirit Realms exert over beings after prolonged exposure inside a realm. The influence itself is called Control, which varies from realm to realm.

Control in the Spirit Realms
The following is a short description of each Control found in the Spirit Realms.

Jigoku
Jigoku has the most notorious form of Control, which is known as Taint. Unique among the different types of Controls is the Taint's contagious nature; no other realm's Control has the ability to spread from an inhabitant to inhabitants of other realms. In addition, the Taint also grants the bearer a variety of powers, making it one of the most versatile Controls.

Jade is the only known protection against the Taint.

Gaki-do
Gaki-do's Control has no name, but is still powerful. Once it has taken hold in an individual, it will soon wipe away all conscious thought processes until all that is left is the desire to consume.

Crystal can be used to protect oneself from Gaki-do's Control.

Sakkaku
Sakkaku's Control has two stages: chame, which is the initial Control and has the effect of reducing one's self-control, and fuzen, which turns the visitor mean-spirited and harmful.

A smooth round stone from Ningen-do provides protection while in Sakkaku.

Meido
Meido's Control, which is unnamed, is the most powerful of any realm's Control. Upon arrival to Meido, it renders the visitor devoid of all emotion and need. However, the Control quickly and completely fades once the visitor leaves Meido.

There is no known protection from Meido's control.

Yomi
Yomi's Control is probably the second most well-known Control to the people of Rokugan, thanks to the Battle of Oblivion's Gate and subsequent War of Spirits. The unnamed Control manifests itself in a brilliant halo that surrounds the entire body, even when wearing clothing. It is also tied to one's sense of honor, and will glow brighter or dimmer depending on the strength of the bearer's honor.

There is no known protection against the Control of Yomi, although one could resist it out of sheer willpower if they wanted to do so.

Tengoku
Tengoku's Control, also unnamed, suffuses the visitor with the lawful nature of the Celestial Heavens, moving them closer to the tenets of bushido and orderliness of the Emperor's Law.

There is no known protection against Tengoku's control.

Chikushudo
Hitsu, the Control of Chikushudo, slowly turns the visitor more feral and bestial until he or she loses all sense of honor and becomes nothing more than a wild animal.

Items made of steel, such as swords or armor, provide protection from Hitsu.

Toshigoku
The Control of Toshigoku, also known as Satsugai, shrivels and grays the body while filling the mind with bloodlust until eventually the visitor becomes a member of the Legacy of the Forge. Some individuals, such as Hantei XVI, have remained in Toshigoku for centuries and yet have no fallen victim to Satsugai (although they remain quite insane). The manner by which they protect themselves is unknown, although it may be a unique quality found inherently in certain people.

Crystal provides protection from Satsugai.

Yume-do
Yumeji, the Control of Yume-do, is unique in that it affects only native inhabitants of the Realm of Dreams and not visitors. For more information, see Yumeji.

Yumeji can only be gained by those who seek it, so by definition no form of resistance exists except willpower.
