You are an assassin. Born to be a weapon. Your name is Xera Caelan. Beautiful as the moon, deadly as the Sun. You disguise yourself as a noble to kill other nobles or to kill royal. Few hours ago, you are given a mission to kill the Xist Kingdom's king, Kai Xenan.

No assassins has ever been successful killing him as they always disappear without a trace. The King has always been cold, cruel and heartless.
