Blade of Heaven is a manhwa fantasy-adventure series written by Yong-su Hwang and illustrated by Kyung-il Yang, published by Daiwon C.I.

The North American version of the manhwa is published by Tokyopop and distributed in Australia and New Zealand by Madman Entertainment.

Before all of this began however, there was a certain period of time commonly referred to as the "Great Battle of Heaven" before human beings supposedly had existed.

This vicious sword had been known to have left many levels of blood in its ruthless wake, and particularly chose those of high status as its master.

The previous renowned wielder of this sword became referred to as King Pachun (who unknown to Soma is his father).
