Wild Arms 5

Humans are currently being ruled over by the Veruni, an alien race that landed on Filgaia 100 years ago. Dean Stark, the protagonist of the story, lives in a secluded village away from all the turmoil. He dreams of one day leaving the village to pursue his dream of becoming a Golem Hunter, someone who excavates ancient robots, like his idol Nightburn. While in the mountains, Dean and his childhood friend Rebecca spot a Golem's arm fall from the sky and land in a cave just in front of them. (imdB)
