In the era when dragon slayers and great mages still emerged among humanity, artifacts born from ancient magic and the blessings of the gods wielded tremendous power. Some of these included cursed swords that could slice through iron as if it were paper or potions that, when consumed, could restore youth. Among them, there were even elixirs that granted immortality or relics that could allow a person to transcend the limits of mortality and ascend to the heavens.
Naturally, everyone coveted these treasures, both in ancient times and now.
—"What does life matter? If we can steal this, it'll change everything!"
Heroes were constantly plagued by thieves of all kinds. Despite the owners' strength, human greed often blinded individuals to their own mortality. It might have been easier to entrust these treasures to someone else, but the problem was that there was no one trustworthy enough to safeguard such power.
