As Martin kept killing the Mantis Army with his use of energy and other types of sword origin, some things started to change. The Mantis Army and individual Gold Sand Mantis were not that smart or had any intelligence other than battle instincts. But everything comes from somewhere and there is some being that gives life or birth to these mantis and there is no chance for it to be not smart at all.

Inside the deep, dark underground, there was a large open space. On this open ground, a magnificent castle stood up.

Tall windows are scattered generously across the walls in an asymmetric pattern, along with overhanging crenellations for archers and artillery.
