Sword Art Online-Vol 4 Chapter 0: Prologue

Prologue

Looking up, there were many lights shining beyond the dim sky.

Those were not stars. They were countless icicles that hung from the vast ceiling and emitted a faint phosphorescence contained inside them. In other words, this was the bottom of a cave, and its size was the problem.

The distance to the faraway towering cliffs was, in real world distance, probably 30 kilometers. The lowest height till the ceiling was 500 meters. A countless number of carved cliffs and ravines, frozen-white lakes and snowy mountains, and fortress and castle-like structures could be seen at its bottom.

With that, the scale of the cave was unbelievable. This underground space, no, it should be called the «Underworld».

Actually, it was just that. This was another field that filled the undergrounds of the fairy world, ALfheim, a dark world of ice and snow, ruled by dreadful evil-god-class monsters. Its name is—

«Jötunheimr».
