Encyclopedia Entry:
They’re one-eyed monsters who live in seclusion in the mountains. Originally deities, they were scorned by some other gods because they only had one eye, and they were cursed and became monsters. Due to the devil’s influence, their ability to reproduce has been increased to that of a human’s. Cyclops are docile monsters who don’t talk much, nor do they show much emotion on their faces, so it’s hard to tell what they’re thinking about by looking at them.
Most of them are blacksmiths and would occasionally sell their wares in the market via their familiars. But to ensure that the weapons they bought were indeed crafted by the cyclops, many famed warriors would travel into the mountains themselves and pay the cyclops a visit.
