They returned to the past where time was not relative which was when they were in upper draconium because the artifact messed with time. So everything that happened when Han Bin left did not happen because he went back to the others and avoided everything they did wrong in the past. So now this is when the present isn’t following the past anymore because omphalos knows there’s a regressor

So atisse and ryu han bin returned to the passed… and then what exactly? Back to upper draconium? I don’t get it ╥﹏╥
