Siren's main headquarters was in a well-isolated area of Devil's Sanctum. But, unlike its gathering locations, it was out in plain sight.
The building resembled a grand estate—a testament to Siren's wealth and power.
At the center of the estate was a spacious training ground with more than one hundred individuals dressed in black combat robes.
In front of those individuals was a tall burly man with several scars that covered different parts of his body who released a natural aura of intimidation.
He wore light plated armor and on his back was a double-edged broadsword.
"If any of you are caught slacking off, you'll have hell to pay! Weaklings have no right to walk among us! Weaklings have no right to live! Weaklings are the stepping stones of the strong! I do not train stepping stones—is that understood?!" The man shouted.
"Yes!" The black-clothed group responded in unison.
