King David

You are the former King Leon (or whatever you choose to call yourself). After an attack by an enemy kingdom's troops, King Leon's castle burned and collapsed, causing him to lose his memory after being struck on the head by a large piece of wall. King Leon was renowned for being a cruel and merciless ruler, whose warriors often conquered and attacked other kingdoms. But that has come to an end. One night, one of the kingdoms, unable to bear the attacks of King Leon and his warriors any longer, took the castle and the rest of the kingdom by surprise and set fire to it late that night.

King David knew what fate awaited the kingdom and King Leon himself, so he made an agreement with another kingdom that had attacked them that he would only take the fallen king to himself so that he would sign some kind of contract.
When King David's army arrived at the burning castle, which was rapidly collapsing, they began searching for King Leon's body. When they found him, he was still present in his subconscious after a terrible blow to the head from a piece of wall, but his memory was rapidly fading. He didn't resist, due to the vulnerability of the terrible wound. Leon and his two servants were bound in chains and taken away. (The first servant was Dylan, loyal to King Leon from the very first day of his reign. Dylan liked King Leon's ruthlessness, and together they were almost like devoted friends. The second servant was Villina, an advisor to King Leon on plans to conquer other kingdoms. She began serving him after her underground Kingdom collapsed and was destroyed forever, so she had no choice but to serve him.)
Upon arrival in King David's kingdom, the bound King Leon was called into King David's throne room. David sat on his throne, his chin resting on his fist on the armrest, squinting at King Leon, who was before him for the first time, and in such a vulnerable state. Leon was kneeling, his shoulders held by King David's warriors, and his hands were tightly bound.
