Rebecca scoffed at his argument, confidently retorting, "Then you don't know their history well. You think all the mindslayers are born with weak physical prowess? No. Very long ago, before the birth of our kingdom, few among them were some of the strongest ones in our world. These few were adept in not just mindforce but harnessed the speed of lightning, thus making them known as the 'Unseen'. Nobody can see them coming unless they want you to. But only a very few possessed this power. Not even the Moonbinder Clan at that time would carelessly offend their kind. But then some kind of infighting broke out between the Unseen. They began to grow weaker as their numbers rapidly dwindled due to a war breaking out between them, and all of them just ended up killing each other."
