Enemy of the Oracle: Picked up and Taken Home by an Elf Girl at the Beginning

"Call me sister! I'm only fifty-five years old, and I'm still a beautiful girl among elves!" Cather faces daily corrections from her good sister Lista (who calls herself) Lista told him that he was a baby who was picked up by the Elf Ranger fourteen years ago and returned to the "Iron Felt and Furnace" mercenary group. But in the mercenary group, he vaguely learned that fourteen years ago, "Iron Felt and Furnace" received a mission to find the remnants of the Plantagenet royal family. When he was twelve years old, some large memories that did not belong to him suddenly appeared in his mind, and the world became a little strange in his eyes, with "ethereal sounds" that appeared and disappeared inexplicably, and strange white and black lights on the creatures... However, this did not have a big impact on him. He always considered himself "Kaiser Silvermoon", a boy who was raised by a mercenary group - even though he looked a bit not like a "boy". He originally thought that his life would last forever in this wonderful family composed of an unreliable elf, a reliable leader, a grumpy dwarf couple, a silent orc warrior, and a door-knocking human mage. However, the gaze of the gods did not go away. When the Judgment Knights of the Holy Court encircled and suppressed them, and when cold wanted notices were posted in every town in the background, he was shocked to find that this small mercenary group was just an ant that could be crushed at any time under the ruthless violent machine of the Empire and the Holy Court... (Newcomer, I want to tell a growth story with a royal approach, "light system". The first part focuses on the warm daily life of the mercenary group, and the follow-up will expand to a larger stage and world.)
