→Barian's Door
Five years before the events of [[World Duel Carnival]], [[Dr. Faker]] conducted research about finding the doorway to [[Barian World|other dimension]], assisted by [[Vetrix|Byron Arclight]]. With [[Kazuma Tsukumo]]'s help, they located the remaining two of twenty-three odd phenomenons in the world, which allowed them to pinpoint the location of the door. After finding the door, Faker betrayed both Byron and Kazuma, sacrificing them to enter the [[Barian World]].<ref name="ep56">{{episode|Yu-Gi-Oh! ZEXAL|56|ref}}</ref>
On the other side of the door, Faker encountered the [[Barian (species)|Barian]] emissary [[Vector]], who agreed to heal Hart in exchange for Faker destroying the [[Astral World]]. Vector sustained Hart's life with his powers as Faker worked to complete the [[Sphere Field#Sphere Field Cannon|Sphere Field Cannon]] and collect the "Numbers". If Faker did not succeed, Vector would take Hart for himself.<ref name="ep70">{{episode|Yu-Gi-Oh! ZEXAL|70|ref}}</ref>
When [[Misael]] performed a [[Chaos Xyz Evolution]] using his "Number" monster, a door similar to this one appeared in the process, though it had the [[Barian Emblem]] on it.<ref name="e83">{{episode|Yu-Gi-Oh! ZEXAL|83|ref}}</ref>
