Aincrad is a vast land. Home to many diverse people, strange creatures, and dangerous monsters. Hidden among the dense forests' shadows, beneath sands of blistering desserts, and frozen within the mountains, far into the north, are secrets which have eluded people's comprehension for eternity. But now, a dangerous being, the Lord of Blood, has placed all of Aincrad under his thumb. But the humans and fairies of the world resist his madness and must fight if they are to protect their home.
