Lords of Fluviallis
Gates of Endless Worlds
During the Age of Creation, only the Aboleths, Vault Builders of Orv, and the Dragon Lords dwelt upon Golarion. It was during this time, before the Age of Serpents, that the Fey Lords created the Gate of Endless Worlds on Golarion. They built it here because the primal magic of the First World was too dangerous and unstable to risk building a permanent series of gates. They completed their task and spent many years after moving through the Gates, exploring worlds to suit their whimsy and curiousity and ease their boredom. After an Age of exploring, they decided that some things beyond the Gates were too dangerous and the Gates were no longer used. The Fey Lords sealed the gate by appointing a guardian from each court to prevent its use.
According to Kintaro, at some point in the distant past, elven wizards managed to breach their defenses and trap the three guardians. What happened next is unclear, though Kintaro did say that being from the Dark Tapestry came through the Gates and fought with the elves, driving them from the area. Kintaro and the other Guardians are members of a group of First World primordial beings known as the Tane.
