A/N: Fire Emblem isn't mine. It belongs to Nintendo.
"You can't be serious!" snarled Chrom angrily, he turned to his sister. "Please, reconsider! I beg of you, Emm!"
"Oho, I thought Ylisse was seeking peace?" said King Gangrel's Right-hand. "We offer you a peace treaty and now you claim that we have foul intentions? Were all those speeches about peace a complete lie, O Exalt?"
Emmeryn kept her face pensive as she carefully surveyed the contract in detail. It was everything that she had yearned for, except…
"If you so wish it, we could shift arrangements so that your younger sister is the one chosen instead," said the Right Hand. Gangrel sat quietly on his posh chair with a smirk adorning his features. He enjoyed watching the Ylissian barbarians squirm as they attempted to get out of this generous peace offer. "Of course, she has no mark of royal birth so you would have to offer us something to compensate for your impure kin. That worn royal trinket should suffice."
Emmeryn froze for a tenth of a second. Gangrel forced himself not to snicker in glee. They wouldn't give that up regardless of what the penalty may be. The prissy bitch's speeches about peace only extended so far as keeping the royal coffers safe while letting her people get looted and killed by his Plegian forces. Now, Plegia had changed tactics and brooked a peace agreement. Emmeryn was forced to accept meeting them in Plegian home territory and accepting Plegia's own version of the 'peace process' or else Emmeryn would appear to be a sham to her own people. Gangrel jubilantly contemplated the irony of how a peace process could be just as damaging as a war mandate. Patronization was the most powerful form of politics, after all.
How his Right Hand so shrewdly attacked the prissy blonde bitch's family with his sharp tongue! Bringing up a deep-seeded personal shame of Emmeryn's little sister, then suggesting that the little minx be carted off as damaged goods for the sustained peace of both nations. The man before him was both a political and tactical genius in every respect. Gangrel admitted that his Right Hand had humbled him in many ways over the course of a few short months. Plegia was now on the verge of a golden age because of him.
"That is unnecessary," said Emmeryn after a lengthy stretch of silence within the room. "I accept these ironclad terms. I trust that peace shall be ensured between our nations once I've begun preparations."
Emmeryn signed-up the document in one fell swoop. Gangrel couldn't hold it in any longer. He burst out laughing in his chair. Aversa smiled in glee at the transpiring events. The Right Hand accepted the document back and handed it to Gangrel to sign off.
"Sister, no! There has to be a better-" Chrom was cut off.
"Hold your tongue, Prince," said Emmeryn in a clipped tone. She was forced to pull rank to temper her brother's seething rage. Chrom felt his anger wilt as he saw his older sister's pleading eyes. "It would be best that you conduct yourself in a manner befitting your noble status. You shall rule Ylisse from henceforth and must remember your own importance."
Chrom looked down at the floor in anger, Lissa buried her face in her hands and openly wept, and Frederick closed his eyes in solemn acceptance of Emmeryn's selfless judgment.
Emmeryn peered toward Gangrel and bowed deeply. Gangrel had just finished signing the document and openly laughed at the prissy bitch's humbled posture. Oh, victory was so sweet!
"I shall begin immediately as an act of good faith to ensure our commitment," said Emmeryn to the Plegian diplomats, "…It shall be my pleasure to serve as your noble concubine from henceforth, Milord."
Gangrel clapped his Tactician on the shoulders in acknowledgement for his services. The Tactician had one more strategy to make just to add salt to the wound.
"Do not dawdle," said Robin smoothly. Chrom glared at his newly hated rival in anger. The upstart had got his sister sold to the enemy for 'peace'. "Both our citizens' lives shall be in continued jeopardy until you arrive at Plegia's capital. Make haste, good lady so that you may fulfill your wifely duties."
Chrom clenched his teeth at that. He loathed himself for being unable to do anything and swore to never forget his sister's noble sacrifice for everlasting peace between the two nations. He knew that any attempt to take Emmeryn back now would be an act of war.
Gangrel made a show of staring at Emmeryn lecherously. Gangrel decided that after he had his fill and she bore him a child that he would send her off to other nobles as a persuasive tool. The peaceful and serene reputation of the former Exalt would do well in getting men hardened to want turns with her.
Everybody knew that Emmeryn would do what she always did. She would strive towards peace for her beloved countrymen at whatever punishment and cost to herself. The peace brooked by this agreement would be one that was hailed throughout the ages by both nations.
