In a lab on a random planet in a test chamber with a giant test tube, with four divine creatures inside. they are an immemorial wood tiger of the finest quality, a void wolf with the king's bloodline, a pure celestial heaven fox, and a rare elemental dragon with the bloodline of the king and the time dragon. As time passes they start to fuse and come onto one entity, even the souls weren't spared in the fusion.
As the process was in the final stage, the entire lab was stolen by rebels of the race. As the process finished, a chaos calamity struck the new creation to destroy it. During the calamity, everything that was trying to destroy it got absorbed into the body to create a new core. also creating a innate connection to the artifact that was containing the lab.
It was left unchecked until the day many hundreds of years later, some descendants, of the thief's who took the lab, was sent to organize the inventories of each stolen item.
