Among all the races of Elfes, the Blacks are probably the most worrying. Dark and silent killers veiled with mystery, no one knew their origins so far. Whether they are born Blue, White, Green, Red or Grey, their true nature is revealed only after a few years... Gaw的er is a young Elfe Blue with warm blood. Watching for a long time the suspicions of his father, he does not slow to be detected and taken away to his family to be led to the Citadel of Slurce, the Fortress of the Black Elves. Located in the distant massif of the thorn, this is where all the Black Elves are taken and educated as soon as they are spotted by the flappers. Gaw的yn, thus baptized upon his arrival, then begins a long and painful learning to become a skilled and ruthless killer, perhaps the best among them... But a strange noise is heard at night... a chilling and terrifying noise that will cause trouble in the young apprentice.
