"The territory I'm in right now is the home of the Lvl 103 One-Eyed Cyclops, otherwise known as The Herder."
From what information Romulus could gather with his S-Rank Discerning Eye Skill, the One-Eyed Cyclops got its secondary name due to what it did as a human and what it was still doing in the present. Specifically, it herded — it was a herder. Thousands of A-Rank Monsters were the cattle in this situation, and they were all tasked with guarding the territory dubbed 'Odysseus's Grave.'
In this timeline, there were a few Heroes that arrived in Utavia from a different world. One of those Heroes came from a period long ago, and was known as none other than Odysseus. However, upon arriving in this world after experiencing his supposed death, the great hero Odysseus realized that he was far outmatched. Yet, as the Great Hero, he could not just give up. Therefore, he trained. He trained harder than any of the other Heroes summoned by Holy Goddess Valeria.
