Legion20
crazy theory... but as both lith's primary elements are darkness and fire, and he is bound to become the guardian of destruction or something like that, is there anyway he finds a way to kill Night for good? untill now, the horseman can not be killed, only sealed with the help of mogar on the fringes, like dawn was sealed in the werewolf people village (sorry if i got something wrong), but Lith's next tribulation could be this fight, requiring Lith to be the first one to ever kill a horseman.
