Biocores: The Legendary Weapon Designer

A couple of months ago, this same group of people had gathered to mock him on the day of his arrival. Now, they were bowing in acknowledgment of his strength. He remembered the advice he received from Marsai: "Your only viable path is through domination. To convince people of your worth, you'll need to subdue them."

"The witch was right," he thought as he walked forward and was immediately flanked by the trio. A tactic understanding was shared between them as to what the chain of command was on this mission.

Narnia was a storm-ravaged island surrounded by crashing waves and jagged cliffs. The dense jungle provides cover, while parts of the island have been flooded due to the feral biocores water-controlling abilities. After taking control of the island twenty years ago, it established its nest in the ruins of the old command base.

Cyanide presented a screen to Nioh that displayed the state of the ruins and the location of the Feral beast.
