for this do you mean "you want suggestions for what lore to put in the game" or "how the current lore is working"?

Both really, any suggestions are welcome :)

okay how about the shadow warrior, a boss that you can only get to by "following the shadows", having the shadows projected in random directions pointing to doors after following them for a set amount of time that will take the player to a scret level, to face the shadow warrior. The shadow warrior was a lady assassin that was so good most of her assassinations that there were no sightings of her around or at the sight. the only way they knew for sure it was her was an outline drawn on the ground to mark the shadow drawn at the time of death. however, on here last job, the death of an empirer, she was caught, dressed as a common severant. As a result she was excuted. now her sprite allows her to controll any shadow, but she is unable to leave the dugen with out a human host to hold sheild her from the sun so she can take revenge on the empirer that took her life.

1) How about a poison or virus is growing in the people of this place (to be named?) and you are one of the infected. You have to find a cure, but you soon find that this was intentional. You have to find others, and see if there are immune people/cures. You find "something" but you go back to your city/village/town (when is this set?) but everyone is DEAD. You must stop whoever is doing this before it spreads to other places.
2) You are a simple man, who has no experience in battle, but you are dragged into the world of battle and war when your last momento of a friend/family person is stolen. You are probably mentally sick, and others see you as a glass cannon, ready to explode. Soon enough the momento is destroyed, and you kill a comrade. You are banished for a short time before you join back into battle.

Yeah, also, when/where is this game set? Middle ages, future, ect?
Also, I would like a key, but hey!

a kid looking for his father and the only way to find him is to defet the evil mastermind
