Lan (Chinese: 岚 Lán), also known as the Reignbow Arbiter (Chinese: 帝弓司命 Dìgōng Sīmìng) or god of the Skybow (Chinese: 天弓 Tiāngōng), is an Aeon in Honkai: Star Rail representing The Hunt.

Description[]

"With no end to hate and no boundaries to war, how much concern do you shoulder? With determined eyes and the arrow drawn, the Reignbow Arbiter needs not turn back hither."

— Worlds History as a Mirror, Xianzhou

The Aeon known as the Reignbow Arbiter wanders endlessly between worlds to destroy the undead beings that once poisoned their homeworld.
The cost of the hunt was never a consideration for Lan. There is often no difference between the salvation they offer and total destruction.

Profile[]

Lan harbors an intense hatred towards Yaoshi the Abundance and the Denizens of Abundance supported by THEM. THEY tirelessly hunt them down, driven by the devastation the Abundance caused on THEIR homeworld.^[3]

In contrast with the other Aeons, Lan pays close attention to mortals.^[4] Although the Simulated Universe Index says that Lan often appears before mortals, Fu Xuan says that THEY rarely appear before mortals and "the only portents of THEIR presence are vestiges of the Lux Arrow tearing across the sky."^[2] The Record of Reignbow's Road says that "Reignbow would never speak to any mortal... THEY only let their Lux Arrow do all the talking."^[5] According to Welt, Lan does not rank among the more powerful Aeons as THEIR path is very narrow, but THEY pay close attention to mortals. THEY grant strength to the Xianzhou Alliance without reservation, allowing their marshal and six generals to stand on par with the Lord Ravagers, Emanators of Nanook the Destruction.^[4]

Appearance[]

Lan is described as a tall, valiant prince with a crown in the Simulated Universe. THEY possess centaur like features, taking form of a man combined with an equine below the waist, while the hind legs are replaced by wheels of a chariot.

History[]

Origin Myth[]

A Xianzhou origin myth found in the "Ode to Reignbow Path" describes the pre-ascended Reignbow Arbiter as an anonymous Xianzhou hero. This is believed to be historical truth by a minority of academics. However, there is no factual evidence to show that the hero is Lan. Although the Xianzhou Alliance has never outright denied the myth's authenticity, their unclear stance on the subject has been taken as an implicit denial.^[6][7]

The Reignbow Arbiter was originally not a god, but a mortal born before the Three Sufferings era. Based on historical records, they were born in approximately 1700 Star Calendar.^[8]

At some point in the past, they led the Xianzhou army against the Heliobi, who formed a red micro-star to capture the Xianzhou fleet. A suicide squad led by the Reignbow disassembled and weaponized the auxiliary engine of the Xianzhou Yaoqing, and sent straight into the the red star, causing the star to undergo early decay and implode into a black hole. After their victory, the Xianzhou army locked up the defeated Heliobi leader, the Flint Emperor, sentencing them to serve as the power source for the Xianzhou Zhuming for the rest of their eternal life.^[8]

The planting of the Ambrosial Arbor on the Xianzhou Luofu brought celebration and joy for the immortality it promised. However, the Reignbow foresaw the devastation that mara would cause to the Xianzhou, possibly with the help of the Wisdomwalker. When they tried to warn the others of this future, they were mocked and labeled as insane. To show their resolve, they shot the Ambrosial Arbor — an act they would be convicted for. The aristocrats who had eaten the fruit of the Arbor were enraged, but as they still respected the Reignbow's heroic exploits and prestige, could only sentence them to continual hibernation in cryo-sleep pods.^[8]

During the "Flaming Catastrophe," one of the Three Sufferings of the Era of Bloodshed, the Xianzhou Alliance encountered the tree-planet Muldrasil, which gravitated towards the Luofu's Arbor. War broke out between the Xianzhou and Muldrasil. Fatigued from their civil war between the coarse and the nobility, as well as the aurumaton rebellion, the Xianzhou decided to release all prisoners of the cryo-hibernation from their slumber to help them fight. Among the released prisoners was the Reignbow. Once awakened, they descended into the prison deep within the Zhuming and made a deal with the Flint Emperor, allowing them to possess their physical body in exchange for the power of Heliobi.^[8]

Inspired by the Reignbow’s sacrifice, many Xianzhou residents made the same deal with heliobi and formed suicide squads to fight in the war against Muldrasil. The Reignbow took position from the bow of the Yaoqing and shot an arrow enhanced by the power of the Flint Emperor.^[9] The force of their star-shattering shot was so great that it affected every ship of the Xianzhou Alliance, as "blood rain poured upon the Xuling" and "nights turned crimson on the Fanghu." The arrow smashed into the Ambrosial Arbor and severed its connection to Muldrasil, greatly wounding the planet. This ripped open a fissure into the void and a monstrous wave of imaginary force spewed from it.^[8]

Based on historical records, the Reignbow disappeared after shooting that arrow, although the Flint Emperor had left behind part of their body.^[8] It is believed that the Reignbow saved the battle at the cost of "self-burning," and they ascended to Aeonhood after their death.^[9]

Star Calendar[]

In Year 3400, the Reignbow Arbiter appeared for the first time and severed the Ambrosial Arbor with THEIR Sky-Shattering Lux Arrow, saving the Xianzhou Luofu from the Muldrasil and the wingweavers.^[2][7]

In Year 4100, the Reignbow Arbiter became the undisputed main Aeon of the Xianzhou Alliance, displacing the Xianzhou's previous worship of Qlipoth.^[10]

In Year 7900, the Yuque's Cloudpeer Telescope managed to detect Reignbow's manifestation. Trace elements pointed to three coordinates in the Consternation Starzone: The Yadav variable star; the Cerulean Nightmare; and the Knucklebone. Using the Matrix of Prescience, the master diviner predicted that it must have been plagued.^[5]

In Year 7954, the Cloudpeer Telescope managed to detect traces of Reignbow's Lux Arrow nearby Laevateinn-XVI. When the Cloud Knights' Vernalbolt Fleet arrived at the coordinates, the planet had been destroyed without any survivors remaining. It was categorized as a "deadworld," and deleted from the astral charts.^[5]

In Year 8072, during the Third Abundance War, Fu Xuan came up with a plan to ship the Cloudpeer Telescope to the Xianzhou Fanghu, which had fallen victim to a surprise attack from the Denizens of Abundance. Jingtian, former Master Diviner of the Yuque's Divination Commission and the only person who had the permission to use the telescope, sent out an SOS signal to the last observed location of the Reignbow's Lux Arrow.^[11] Yueyu, former Arbiter-General of the Yaoqing, defended the telescope till her last moment.^[12] The Reignbow descended onto the battlefield and fired THEIR Lux Arrow, annihilating the borisins' fleet and turning the tide of the battle. However, the supreme destructive force of THEIR divine arrow destroyed nearly one-fifth of the Xianzhou Fanghu's delves.^[5] Within these delves was the field hospital Yufei, an Alchemy Commission healer, was stationed at.^[13]

Amber Era[]

In AE 2131, the astronomical observation system detected a spacial disturbance left by an entity traveling too fast to be measured. Shortly thereafter, a flash of light cleaved apart the sky, leaving behind abnormal rainbow-colored traces. Half a unit of system time later, the entirety of the planet Xuange imploded. Xuange's inhabitants were affected by the molting disease and the planet's destruction was attributed to the Hunt.^[14]

Present[]

At some point of AE 2158 (Star Calendar Year 8100^[15]) during the Luminary Wardance Ceremony on the Luofu, when Feixiao confronted Hoolay in Inner Beast's Battlefield, they debated on the reason they fight knowing that Aeons never answer the mortals. She answered that she fights so that one day she will never have to witness another Lux Arrow falling to the ground and so that just one more person can live and return to the Yaoqing alongside her. She prayed that the arrows of The Hunt will pierce the heart of every monster even if Lan does not respond to her. As Lan witnessed her determination, THEY gazed at her and sent her axe to the battlefield like a shooting star.^[16]

Abilities[]

Sky-Shattering Lux Arrow[]

The Sky-Shattering Lux Arrow is a projectile weapon shot by Lan that can shatter stars light-years away. Shards of the Lux Arrow can be reforged by the Furnace Master, chief of the Xianzhou artisans, for those who are worthy.^[17] At the end of the Third Denizens of Abundance War, the Reignbow Arbiter's Sky-Shattering Lux Arrow wiped out everything along the way. The Xianzhou people used the burning embers of the arrow to create many divine objects.^[18] The Lux Arrow is the only known material that can harm the Ambrosial Arbor.^[19] The arrows are made with stars and shot with gravity.^[20]

Spiritus of Arbiter-Generals[]

Each of the seven Arbiter-Generals possesses a Spiritus (Chinese: 威灵) granted to them by Lan.^[21]

Dev Log1[]

...Lan, on the other hand, often appears before mortals. However, THEY move too fast, and very few observations have been made about THEIR actual form. Most of the reliable information is kept by the Xianzhou Alliance and it took me a great amount of effort to get. As one of the rare factions in the universe that is completely blessed by an Aeon, the Alliance stands on equal grounds with the IPC, which meant the IPC couldn't help me at all. In the end, Ruan Mei had to step up to help. In the ancient Xianzhou language, "Lan" means "an unpredictable fog," and the Aeon's formal name in Xianzhou is Reignbow Arbiter. According to Xianzhou natives, the Lux Arrow of The Hunt showed them the way as their civilization was about to fall...

Dev Log2[]

...How would you describe the Aeon of The Hunt? We can get an impression from the Xuange Observation Station's report in AE 2131. The astronomical observation system detected a gravitational wave, a spatial disturbance left by an entity traveling too fast to be measured and covering astronomical distances. Shortly thereafter, a flash of light cleaved apart the sky, leaving behind abnormal rainbow-colored traces. Half a unit of system time later, the entirety of the planet Xuange imploded. The bad news was the IPC lost a planet in its business sphere. The good news was the IPC was out of ideas regarding the molting disease (undoubtedly the work of Yaoshi) spreading throughout Xuange. The light permanently "healed" that planet and the patients on it, a race of immortal half-human half-snake monsters. This is the action and creed of The Hunt, for whom salvation and destruction are nigh indistinguishable. Their perpetual enemy, the Abundance, is the same, for THEY bring healing and torment hand-in-hand...
