According to the quest instructions, the most straightforward method would be to take Hazel out of the city and flee, only needing to delay until the new empress candidate appears. However, this would likely spell trouble for his human mount, Drunken Dream, who would face severe consequences.
If the empress is not from the Xian family, the Xian family, which had been entrenched in the Empire for over a thousand years, would be uprooted. It's possible that Drunken Dream's battle beast, Denoka, could even have its contract forcibly annulled, which would be a significant blow to the forces of future trialists.
However, Orson couldn't bring himself to simply hand Hazel—his cute and charming wife—over to the incompetent emperor. Letting this fat pig get his hands on such a precious gem like Hazel was absolutely unacceptable. Clearly, merely following the quest instructions wouldn't be in Orson's best interest.
