"Yes, it is invisible just like the air but it repelled anyone who tried to pass through it." Lyron added.
"Wow!" Naya nodded. That spell was similar to the Invisible Dygeon spell used to hide the Vampire world from her future life, so, Naya quickly relate to what they meant. Just that this spell only prevent intruder while the Dygeon spell hide the entire City. "I—I see" She commented.
"Even though Alpha did not always want a battle or war to breakout but they always initiate it. See those multitudes, they are all intruders that came here as soon as we left. This got to Alpha and let us missed the chance to visit the Sachia kingdom." Beta Walter said.
"Oh! So, all those numerous guards over there are all intruders that were trying to find their way into the Kingdom?"
Lyron nodded. "Walls and gate can be break down but his spell cannot... So don't judge a book by it cover."
