Given the choice - whether to rule a corrupt and failing empire or to challenge the Fates for another throw, a better throw, against one's destiny - what was a king to do?
A stream of memories leading up to the present flows past: The vampire, Raziel, Kain's right-hand lieutenant, spreads his newly grown wings… Kain tears the wings from Raziel's back, and orders his other lieutenants to throw him into the Lake of Dead… Raziel burns until there is nothing left but a husk of tissue and bone, yet is revived… He hunts Kain down, but is unable to complete his revenge before Kain escapes through a portal leading to another time… In the past Raziel learns that things are much more complicated than they seem. The quest for vengeance gives way to a quest for knowledge and freedom - one that he shares with Kain.
But does one ever truly have a choice? One can only match, move by move, the machinations of Fate, and thus defy the tyrannous stars. -- Taken from the Script of LoK: Defiance
