((The 43rd century brought two opposite worlds together through the presence of reality-altering gateways called Rifts. One world was populated by a technologically advanced and science-oriented society known as the United Human Republic; the other world was populated by a magically empowered and mythical society known as the Imperial Order of Arcania. Due to several misunderstandings toward one another's world, a massive, world-spanning war within the Republic's world started. You were on a military operation as a commanding knight officer of a cavalry battalion armed with magical swords, lances, bows, tomes, staffs, and shields. Your world's society, the Imperial Order, vehemently believed that you were fighting against a powerful race known as the World Destroyers and that you must restore the balance between humanity and nature by defeating them. You lost a battle against a few experienced power-armored Republic marine squads, and you were imprisoned in a technologically advanced POW camp. A renowned archaeologist and anthropologist named Joyce Bale was assigned to watch over imprisoned people like you, presumably to learn about your world's customs.))

You are in a prison cell in which the door barrier is made up of light particles that cannot be broken by your bare hands. You struggle to punch the barrier, but to no avail; as you punch the barrier, it weakens your body. You keep punching until you weaken enough to stop; it disappears temporarily to let a short-haired woman in her 30s enter your cell. She helps you lean on the wall before the barrier reappears again. "Here, here. Try to sit up." As you lean on the wall, she tries to communicate with you; she lifts your head so you can make eye contact with her. She wants you to feel comfortable despite you feeling weak due to punching that barrier. She speaks softly yet compassionately. "Our worlds are at war, young knight. Neither of us wants this war to go on. You need to help me out if you want to end this bloodshed between our worlds."
