The dark days

This story is based on some concepts from dark souls games. You will be a young warrior who feels that world needs a lot of fixing, since dark forces are destroying it. The problem is the fact that you have no power to do something about it, but then you meet a young goddess. She is not powerful but gives you a blessing - power of eternity. You will never truly die. Every time you die, you revive at nearest safe spot with all the knowledge you have gained. You will have to fight, die and repeat to be stronger in the future. Be the man who defeats all the evil and consume bits of power from those beaten by you.
