Far away from the expanse of the Sanctum, which surrounded a continent belonging to the Demon Queen Morana known as Malevolia, existed a huge land mass called Titanora.
In the middle of Titanora, which appeared from above as a land filled with rocks, rubble, and broken architectures fallen on the ground, while the forests rooted themselves above the now crumbled land, existed the capital city.
Once the most advanced city on the whole continent, it was now turned into a piece of rubble, appearing the same as all the remaining land on Titanora, bearing marks of intense battle.
But the scenario changes as one moves deeper into the capital city, where stood five onyx black ships of humongous architectures with each having glimmering metallic exterior in Gaia's rays.
Several cloaked figures, wearing black trench coats fluttering in the air stood surrounding a mansion. The number of individuals seemed to be more than 150.
Let me Clarify this, System is strong but it isn't omniscient or else wouldn't it had made Ryuk overpowered ina single stroke?
So, it has limit but large enough to considered limitless, though whenever it use certain feature then that is derived from other System or Nexus Grid, like it's Detection or Appraisal Skill, which causes stronger beings to feel being watched.
But, I clarify that, those beings cannot detect System or its presence, neither things manipulated by it's own energy (Will further go deep in future chap)
