Freedom. Min Yon Sul is so close that he can practically taste it. All he needs is to survive one more tour through the Istor Mines. But as it often does, Fate laughs at the hopes and dreams of mere mortals. For his last tour, Min Yon Sul and his Squad 256 are chosen for the most deadly part of the Istor Mines, Sector 13. The next best thing to a death sentence. Min Yon curses his fate but, unbeknownst to him, deep in the mines lies the key to his freedom. And to much more. The key to his Ascension to the Black Lightning God.
