lightning wears armor (made by ???)
lightning is created by "master" (+ how?)
the antagonist is a necromancer (turned evil? by who?)
(maybe they're brothers) war breaks out between them, one turns evil (or both evil? lightning fights for the wrong cause?)
the master turns to "the smith" to make armor for his "creation" (the smith makes it against his will?)
the history was erased by "the master"
we find out that the main antagonist and our master are brothers, we learn about the past from the necromancer, we learn that master is bad
we fight our master as final bossfight
