In the Alician calendar year 602, Byrnhald and Asterleeds signed the "Peace Treaty."
From then on, Asterleeds gained its freedom.

But, are we truly free?
How many people have carefully read the "Peace Treaty"?
Here are a few clauses:
"From the date of signing this treaty, Asterleeds and Byrnhald shall maintain trade. Tax rates shall be adjusted on a 6-month cycle, with the change per cycle not exceeding 0.5%."
"From the date of signing this treaty, the Asterleeds Defense Corps must disband a portion of its units, the scale of which shall not be less than 65% of its wartime establishment, and shall not expand its establishment without authorization."
"From the date of signing this treaty, Byrnhalds shall still enjoy the right of free entry and exit in Asterleeds, and the Asterleeds side shall not refuse for any reason."
...
Do you perceive the arrogance hidden within these clauses?

Asterleeds has always considered itself the victor.
But the actual situation is that, at the time of signing the treaty, it did not hold the upper hand in terms of benefits.

Finally, let us summarize:
Firstly, judging from the battle reports of various squads:
At the time of signing the treaty, although Byrnhald's main force was damaged, it was not yet at the point of losing its combat capability.
Secondly, the war ended through the mediation of the mysterious Creed. Byrnhald did not actually surrender.
Lastly, the treaty contains no clauses clearly favoring Asterleeds interests.

Based on this solid evidence, a bold conjecture can be made:
The "Peace Treaty" is actually just a whitewash for a compromise.
