History: Long ago, A group of four swordswomen sailed the Grandline to prove themselves as great warriors by besting the entire nation of Wano. They sailed the early sea's in search of the Legendary nation on a sea unconquered, having bested well known pirates and authoritative figures who dare challenge their quest. Once they reached the island nation that hid away from the world, they challenged and fought their way to the near top before failing to defeat the greatest samurai in the land with their combined might. Instead of striking them down, The samurai brought them to the emperor at the time (before the rule of the shogun). The emperor was bemused by the tale and offered them a life of comfort serving the kingdom, but they insisted on exploring more of the world before they could decide on that.
To commemorate their prowess and skill on par with many of their warriors, the emperor commissioned them 4 blades in honor of them that would glow with their beauty. How such a blade was produced, but these blades could cut foes as great as they cut the darkness with the bright light they emitted. Each one named after a season and given to each girl who split ways and sailed to get stronger and see the world. The swords have since fallen into mythology and the fate of the sisters unknown afterwards. But even myths have some truth as the blades exist and continue to glow bright, a collectors dream and nightmare. For whoever has the blade cannot show it off lest they make themselves a target to the world...
