Taikiyan

Taikiyan is an athletic entertainment hub, famous for its Roboball matches, and a mentioned planet in Honkai: Star Rail.
==Description==
On this tiny planet, mountains of carbon fiber and stainless steel once traced the pre-decommissioned outlines of giant ships. Later, several planet terraforming machines descended to the surface and yanked out the decommissioned spaceships in their entirety. The obscure little planet had been transformed by the sport of Roboball, becoming a dazzling athletic hub in the blink of an eye.
The track architects of the Intelligentsia Guild had turned the concept of "racing" into a three-dimensional circular track, the standard length of which is 2.91 kilometers. The flat central area of the track is 5 meters wide, and the curved areas on both sides range from 2 to 14 meters in width. The Roboball players will fly unidirectionally for several laps on the spacious and bright track, accompanied by the sound of whistling and collision, completing the entire game. 
According to actual testing, during high-speed travel on the track, disconnected point light sources will connect into lines with the athletes' visual persistence, and several dimly visible lumens will form an exclusive arclight track. The old scuttling site was filled with sightseeing cruises and bustling crowds gathered in the streets, illuminated by lights and advertisements, slowly streaming into the stadium. Both the home and visitor teams are evenly matched in the massive stadium, and the vociferous audience fills up the dome in countless multitudes. The Taikiyan Stadium has been bright as day from the moment of its inauguration.

IPC Assessors wearing propulsion equipment once fought for high-quality parts below-deck for many years, their lightning-fast figures mutually fleeing from and in pursuit of each other in the corridors of sunken ships. They had formed their own underground rules in the shadows. After the planet was terraformed and renovated, the Traditional Project Department invited sport experts from Interastral Peace Entertainment and requested that they remove all savage elements of Taikiyan's underground rules and transform it into a lucrative competition.
The competition had athletes wearing propulsion equipment and armor, ever-changing three-dimensional race tracks, and physical clashes that sent sparks flying. Material experts designed a Roboball to satisfy the request: a high-tech iron ball with a diameter of 35 centimeters, weighing 30 kilograms, and of carbon fiber and stainless steel. It constantly chases alterations of the Phase Flame, increasing the unpredictability of the game through its irregular movements. Sports equipment experts followed that by developing a standard-issue propulsion protective armor for Roboball games, allowing top sport equipment and medical organizations to better demonstrate their quality and ensuring the sustainability of a stable income and safe competition.
And thus, the Taikiyan Roboball Association was formally established, and the initial version of the Taikiyan Roboball Game Rules was formulated. The game system comprising two teams with seven players each was also established from then on. Interastral Peace Entertainment invited the wealthy to participate in the league, promising them the exposure their favorite sport deserved. Subsequently, the league clubs were established, and the most talented players were assembled and ready to go.
Interastral Peace Media had exclusive broadcasting rights for the event and, with the help of ultraremote sensing technology, they broadcasted the live competition far and wide. The sensory experience of top athletes was also recorded throughout the event, allowing homebound viewers to also experience the speed, collisions, whistles, and arclights of the competition from the comfort of their own homes.
Both the home and visitor teams are evenly matched in the massive stadium, and the vociferous audience fills up the dome in countless multitudes. Outside the dome, the planet is also bustling with activity as broadcast licenses, exclusive sponsorship, and advertising contracts are fought over in the trading market, while underground betting is rife as excitement and disappointment share the spotlight in equal measure.
==History==
===Past===
Planet Taikiyan was once an IPC scuttle site for spaceships, where value assessors were dispatched to clean up old ship wreckage for any remaining value. Assessors regarded an assignment to station in Planet Taikiyan as an exile with no return. On this tiny planet, mountains of carbon fiber and stainless steel traced the pre-decommissioned outlines of giant ships, casting a shadow of emptiness over the steel ruins. The exiles' desire to be recalled intensified to a boiling point. Assessors wearing propulsion equipment fought for high-quality parts below-deck for many years. They had formed their own underground rules in the shadows. Despite this, no one was ever able to return.
The rules established by these abandoned humans, reduced to caged animals, did not escape the IPC's surveillance. Footage from their wearable cameras were transmitted back to the IPC and passed as after-dinner laughingstock by the high and powerful. The investor of the Traditional Project Department, however, scented out the faint possibility for "entertainment" after some consideration. With this new plan, the first competition in the galaxy featuring the Taikiyan Roboball would have its debut on planet Taikiyan.
Several planet terraforming machines descended to the surface and yanked out the decommissioned spaceships in their entirety, not leaving a single inch of their former shadows behind. The obscure little planet had been transformed by the sport of Roboball, becoming a dazzling athletic hub in the blink of an eye. Material experts designed a Roboball to satisfy the request and thus, the Taikiyan Roboball Association was formally established, and the initial version of the Taikiyan Roboball Game Rules was formulated. The game system comprising two teams with seven players each was also established from then on.
The track architects of the Intelligentsia Guild had turned the concept of "racing" into a three-dimensional circular track and the Interastral Peace Entertainment invited the wealthy to participate in the league, promising them the exposure their favorite sport deserved. Subsequently, the league clubs were established, and the most talented players were assembled and ready to go. The old scuttling site was filled with sightseeing cruises and bustling crowds gathered in the streets, illuminated by lights and advertisements, slowly streaming into the stadium.
The attention of the entire galaxy was thoroughly captured the moment the Roboball Competition was announced. From that moment forth, the planet once shrouded in darkness has never again seen a moment of night. The inky shade of the night has long been transformed into a silent radium backdrop to the overflowing lights of the stadium, and no one even remembers where the begone shadows are now hidden.
At some point in the past, a group of Nameless rode snowmobiles into the Taikiyan Stadium and disrupted the match, causing the match to be suspended. As a result, Twenty Trailblazers were forced to repair the severely damaged exterior of the stadium for three months without pay.
Pound, a man from Penacony, went to Taikiyan and joined the Roboball competition, in the hopes of earning enough money for himself and his lover Cocona to leave the Dreamscape. He borrowed an inordinate sum of money from The Family and bet that he would become champion in the amateur bracket. However, he lost the championship by a hair's breadth and incurred a massive debt. His fate is unknown.
===Recent===
Director Topaz, Senior Manager of the Strategic Investment Department and member of the Ten Stonehearts, once had a project on Taikiyan, causing her to miss the retirement farewell party of her mentor, Francisco Dvorski. She promised to bring back some souvenirs, as he was a fan of Roboball.
Sometime ago, another group of Nameless aboard the Astral Express smashed a hole through Taikiyan Stadium in an attempt to land directly at the location. They were punished with two weeks of community service.
