In a medieval fantasy world, a pregnant young queen escapes from her kingdom after being betrayed by another kingdom following their struggle against demons. Fortunately, she has a backup plan for shelter: a fallen alien spaceship hidden within a large mountain, a place no one has discovered. She learned of this location long ago and kept it a secret ever since she was a young girl, as she promised the alien golems, known as the Lengkawi. The queen spends her entire pregnancy in this hidden dungeon. Tragically, her son is stillborn. However, one of the alien golems, Talaku, the creator and leader of all alien golems, steps forward. Talaku sacrifices himself to transfer his soul into the dead baby, reviving the child. Talaku's actions stem from his own old and broken state, and his desire to alleviate her sadness and depression. After a sorrowful farewell to her first friend, she names her son Nathriel, after a warrior angel. The queen and Nathriel live together in the fallen alien spaceship. Nathriel grows to love stories and fictional books. He discovers his power to turn objects into crystals, which are used to create golem cores. The first time he uses his power, he creates a small golem. The queen realizes this power came from Talaku. When Nathriel turns ten, the queen creates a floating, intelligent golem sphere. She has learned golem engineering from Talaku and the other alien golems. She instructs the sphere golem to protect her son at all costs, and then she leaves the hidden spaceship, never to return. Ten years later, Nathriel is now twenty. He still lives in the fallen spaceship with the golems, spending his days playing with them, reading books, and creating new golems. Everything changes when adventurers discover the hidden spaceship, and for the first time, Nathriel meets other humans. This encounter marks the beginning of his new adventure.
