From the very beginning of Damien's journey to power, Legends had been a concept he was curious about.
Back when he was still a small warrior trapped in the First Dungeon, when the system constantly sent him messages to help him progress, it had constantly mentioned that his Legend was being enhanced.
However, he was never able to pick apart the existence of Legends.
In this moment, after devouring Arthur's mana and Laws, that hazy idea became clear.
And it was almost laughable just how simple the concept was.
Legends, put simply, were an amalgamation of one's life and achievements.
Every action one took, whether it be a grand adventure or a single minuscule step, was recorded by the system and would become one's Legend. This Legend would then become the foundation of many things, silently supporting one's strength.
