Chaos Hunting Arena

The **Chaos Hunting Arena** is a mountainous region within the Underworld. It is a battleground for for demons to relieve their bloodlust and hone their battle skills. Any participant in the Chaos Hunting Arena is a Hunter (猎人).

## Geography

The Chaos Hunting Arena is surrounded by mountains, which effectively prevents its participant from escaping. There are also mountains with caves within the arena.

For eight hours every day, the **Black Tide** (黑潮) washes over the Chaos Hunting Arena, forcing its participants into caves. The Black Tide is a gigantic mass of a black unknown substance that disintegrates any organism it touches. The Black Tide is drawn towards violence, and will actively move in the direction of physical conflict. A single punch can cause it to inch towards its direction, while an individual's death caused by violence could cause the Black Tide to completely flood a cave.

At the end of each month, several whirlpool-like portals to the human world will appear around the Chaos Hunting Arena.

Sentient "herbivorous" creatures that resemble red blobs inhabit the Chaos Hunting Arena. They primarily feed on remnants of the Black Tide, which allows them to reproduce through splitting. They are regularly killed or eaten by demons in the arena. Ye Yan refers to them as "slimes" (史莱姆).

When night falls, red-capped mushrooms with white stipes known as **Phantshrooms** (幽灵菇) will grow in the caves. Eating them can satiate one's hunger and thirst, as well as enhance one's immunity. When day breaks, the Phantshrooms will wither away.

Xi Sha regularly visits the Chaos Hunting Arena in an enlarged form while sleeping in order to feed on the demons. She appears every day right before the Black Tide. She is referred to as the **Great Glutton** (大食客) by the residents of the Chaos Hunting Arena and will immediately disappear after eating two metric tons worth of flesh.

## Rules

Many rules dictate the Chaos Hunting Arena, and are actively enforced by its participants. The usual punishment for breaking any of these rules is being beaten to death.

* Any non-Hunt King Hunter that stays in a cave during the day is regarded as a coward and will be beaten to death by other Hunters.
* Any Hunter that challenges a Hunt King and either retreats or is struck off the mountain are marked with the **Challenger's Mark** (挑战印记) by nearby Hunters. For one hour until the mark disappears, no one will attack the marked Hunter, but will regard them as a coward until they either challenge the Hunt King again and win or die trying. If the marked Hunter does not challenge the Hunt King by the time the mark disappears, they will be branded as **The Arena's Disgrace** (猎场之耻) since they disgraced the Arena's rules and the honor of dueling a Hunt King, and all other Hunters will stop fighting to kill them first.
* Any female who enters the Chaos Hunting Arena but does not battle will be branded as an **Arena Maid** (猎场侍女), who are marked with black ink on their left upper thigh. Arena Maids wear black hooded robes that cover their entire head and body save for their eyes and left leg. Any Hunter who attacks or harasses an Arena Maid will be beaten to death.
	+ The purpose of Arena Maids are to serve and possibly fornicate with Hunt Kings. As many clans in the Underworld idolize power, Arena Maids view sleeping with Hunt Kings to be a glorious deed that brings honor to themselves, and to their families if they are pregnant with a Hunt King's child. Arena Maids accept full parental responsibility for the child if they are impregnated.

Hunt Kings (猎王) are highly experienced combatants who have at least killed one hundred people in the Chaos Hunting Arena. They are usually indicated by a vertical flag fastened to their back, which they obtain from killing its previous owner. Hunt Kings enjoy many special privileges that are unavailable to others in the Chaos Hunting Arena.

* Hunt Kings may sit atop mountains and eat while awaiting challengers. Anyone who climbs onto the top of a Hunt King's mountain is automatically considered a challenger to the Hunt King.
* Hunt Kings only need to sit atop their mountain for eight hours before they may return to a cave. Hunters are only allowed to challenge a Hunt King during this time.
* New Hunt Kings inherit the hours of their predecessor. For example, if someone were to defeat a Hunt King who has been available for seven hours, the new Hunt King only needs to sit atop the mountain for another hour before being allowed to return to a cave.
* While not an explicit rule and more an informal courtesy, other Hunters will not share a cave with a Hunt King.
* When a Hunt King returns to their cave, Arena Maids from nearby caves will gather to their cave and serve the Hunt King. The Hunt King may choose any number of Arena Maids to serve them. They may also choose an Arena Maid from another cave that is not present.
* While not explicitly allowed, Hunt Kings are the only Hunters who are allowed to be violent with Arena Maids.
* A **Hunt King Duel** (猎王战) is a duel to the death that may be initiated between two Hunt Kings. The winner of the duel must take and wear the other's flag. Hunt Kings with two flags are addressed as **Great Hunt Kings** (大猎王), three flags are **Hunt Monarchs** (猎皇), five flags are **Hunt Emperors** (猎帝), and eight flags are **Hunt Gods** (猎神).
