Ambush

After sparing Wellington's men, Merlin began to consider, what should his next steps be?

At that point, the Holy Dragon Empire had spiraled out of control. Many places were filled with anarchy, and rebel armies were rampant. The Holy Dragon royal family was completely powerless outside of the Holy Dragon City. They were simply unable to control any other place. 

Fortunately, despite the chaos in the Holy Dragon Empire, none of the rebel armies had dared to attack the Holy Dragon City. Therefore, theoretically speaking, the Holy Dragon royal family was still the strongest force. Given sufficient time to recuperate, perhaps the royal family could re-establish their rule over the Holy Dragon Empire.

From this vantage point, there might be merits in supporting the Holy Dragon royal family.
