"Kuro, we've got a problem," Sighed Az, as the door to the throne room suddenly opened and he walked in.
"You didn't knock...this must be urgent," I replied jokingly.
"Yeah, yeah...the detection barrier was breached from the south, and the nullification barrier also responded. Looks like someone's trespassing," Remarked Az with a frown.
"Seriously? Alright, I'm on it...I'm mobilizing all the invisible monsters I've got between the physical barrier and the detection barrier, I'll find them in no time," I responded, before closing my eyes and focusing.
The Wyverns, Lesser Dragons and Krakens are all just a distraction...yes, they do serve as security as well, but as far as I'm concerned, their primary purpose is to distract enemies from the existence of my invisible monsters.
