- This article details the original history before "Chakravarti Divine" era.
"United Sanctuary" (ユナイテッドサンクチュアリ Yunaiteddo Sankuchuari) is one of the nations of Planet Cray, represented by the color yellow. A small nation, United Sanctuary is a holy kingdom of heroes that prize justice and order, ruled over by the Burton royal family of which Alfred is a member. It is primarily dominated by humans and elves, although sylphs, angels, intelligent animals, and deities play prominent roles as well, and cosmo dragons, dragons that embody light and holiness, watch over the nation as its guardian dragons. United Sanctuary has a high level of technology, and combines both magic and science. The nation is bordered by the Dragon Empire to the east and Dark Zone to the south, and is often in conflict with both of them, especially the Empire.
This nation's successor nation during the overDress era is Keter Sanctuary.
United Sanctuary has six clans:
- Royal Paladin, an army of holy knights, sages, and dragons led by the monarch of United Sanctuary
- Oracle Think Tank, a corporation of deities, witches, and priestesses whose business is predicting the future and collecting information
- Shadow Paladin, an army of dark knights, witches, and abyss dragons that have variously been allies and enemies of United Sanctuary at different points in time, but who generally protect the nation from the shadows
- Angel Feather, a medical institution composed of angels that dispatches its doctors all over Cray to tend to the sick and wounded regardless of nation
- Gold Paladin, an army of holy knights, sages, and dragons formed during a period where Royal Paladin disappeared, and has since become the second regular army of the nation
- Genesis, a corporation of deities, witches, and priestesses formed by the leaders of Oracle Think Tank

Originally, United Sanctuary and Dragon Empire were one nation, described as a "grand sanctuary," ruled over by Sanctuary Guard Dragon. However, an ambitious dragon arose and pushed his kingdom towards collapse, and the relationship between humans and dragons quickly deteriorated, leading to a civil war and splitting the nation into two. Eventually, the dragons and a small group of humans allied with them took most of the land, the modern-day Dragon Empire, while the remaining people retreated to the west, to modern-day United Sanctuary.
When United Sanctuary was founded, a machine called the Keter Engine was built, which became the foundation for United Sanctuary's prosperity.
During the time Void was invading the world, the clans of Cray convened to determine who would lead them against the threat, with Royal Paladin and Shadow Paladin coming to blows over which one of them would lead. This started another civil war between the two clans in the Sanctuary, which was resolved when Blaster Dark turned to Blaster Blade's side and gave him his sword, transforming Blaster Blade into Majesty Lord Blaster. Majesty Lord Blaster subsequently killed Phantom Blaster Dragon, the leader of Shadow Paladin, and united the two clans.
Void feared Majesty Lord Blaster's power, so it, through its subordinate Schwarzschild Dragon, sealed away Blaster Blade and Blaster Dark. Without their leadership, Royal Paladin and Shadow Paladin fell into disarray and were dissolved. In response, their remnants joined to form Gold Paladin to fight against Void and free their heroes in the War of Liberation. With the help of Incandescent Lion, Blond Ezel, the captured heroes were released from Void's sealing.
After the War of Liberation, the Gold Paladins were officially recognized as the second regular army of the nation. Many of the knights from the Royal Paladins which were scattered during the War were recruited by Blaster Blade as he founded the Liberators under the Gold Paladins and led by the revived Alfred. Blaster Dark returned to the Shadow Paladins and created the Revengers who operate as an assassination squad for the nation. The United Sanctuary has become the last foothold against the invading Link Joker, a clan created by Void.
At some point in the nation's history, Oracle Think Tank and Sage of Guidance, Zenon foretold the disappearance of Blaster Blade. To stand against this fate, Blaster Blade created the Seekers. However, Link Joker traveled back in time and captured Blaster Blade, leading to an alternate timeline. In the now altered present, Blaster Blade has become Blaster Joker and Percival has replaced Blaster Blade as one of the Liberator's commanding officers. However, an alternate version of Dragonic Overlord, who still remembers the timeline in which Blaster Blade wasn't reversed, created the Perdition faction of Kagero and defeated Blaster Joker, thus returning him to normal. The void then tried to possess Dragonic Overlord, but Blaster Blade cut its seed and scattered it across Cray so that Link Joker will not invade the planet again.
Sometime later, the Dragon Empire's forces, led by Dragonic Blademaster, invaded the Sanctuary. To combat the invasion, Altmile organized an expedition force. Once they got there, Dragonic Blademaster nearly wiped out Altmile's forces. However, Gablade appeared through Stride and chased off Kagero.
Soon after, Blaster Dark "Diablo" and Claret Sword Dragon clashed over leadership of Shadow Paladin, and the latter lost, forming a clique that divided itself from Shadow Paladin. This clique would start yet another Shadow Paladin-created civil war against the sanctuary, with Fenrir allying with them for his own amusement and Gavrail being forced to fight for them due to hostages they had taken. Heroes from multiple nations, including Chronojet Dragon, Ahsha, and Altmile, joined to fight them. In the end, Chronojet Dragon transformed into Chronodragon Nextage to defeat Claret Sword Dragon, with the abyss dragon eventually being killed by its own Stride summon, Aurageyser Doomed. Shadow Paladin was disbanded on paper as a result of the civil war, but they continued to exist in the shadows, returning to protecting the Sanctuary once again.
Hundreds of years after the defeat of Gyze, when Cray's Idea, the source of Cray's deities, was shut down, the Keter Engine stopped working, throwing United Sanctuary into turmoil and desolation, including natural disasters, mismanagement, man-made disasters, and more civil wars. The Burton royal family declined, and the turmoil of the Sanctuary eventually spread across the entire world. Eventually, however, the survivors of these disasters built Keter Gear, a floating island powered by the Keter Engine. Adopting a policy of isolation from international affairs, they renamed the nation to Keter Sanctuary.
- Battle Flag Knight, Laudine, Battle Flag Knight, Constance, Bordgal Liberator, Knight of Festival and Leading Jewel Knight, Salome all have this nation's flag in their card backgrounds.
- United Sanctuary and Dragon Empire used to be one nation known as "Grand Sanctuary". However, after a civil war, the country split into those two nations.
- This nation has the most clans so far - the nation that has the second most clans is the Dragon Empire.
- Booster Set 8: Blue Storm Armada is the only set so far that doesn't have a clan from United Sanctuary in it.
- Ironically, FIVA's United Sanctuary Branch's original philosophy values victory above all else and teaches that weakness is a sin.
- This is the opposite of the nation's depiction in the game's lore, which describes it as a righteous, holy nation.
