So I just had the cinematic where the Mysterious Villon revels her chosen three (Kinda they are shadowy figures). Shadowheart uses the artifact to ward her off.

So at this point my character is thinking enough is enough, I can't just let that artifact fall into the hands of Shar...You know, the powerful evil being bent on maleficent designs.

Now I realize that Shadowheart may be redeemable...perhaps she is a secret agent of Selune herself and she just can't remember (plausible deniability); my character does not know this.

So I am suggesting the option to fight her and take the artifact.

I realize that my character could have done this at the begining, however that is called murder. My character does not have all the facts yet.

BTW in table top, Metagaming is considered taboo and immersion breaking.

Metagaming: making decisions that are based on knowledge your character could not possibly possess, breaking the fourth wall and ruining the RPG elements of the game.
