Oh man, that was deep enough lore it took me a while to remember. The lore for the game was supposed to be a knight who is cursed by a wizard such that he can only leave the castle for x amount of time (your reset timer). Only by saving the princess can you remove the curse. The lock was just the symbol that gets carved on him because of the curse :)
