One common theme is her struggle with her faith. In many fanfics, Shadowheart is depicted as grappling with the teachings of her deity and how they fit into her own moral compass.
Sure. One great Shadowheart fanfic is 'The Redemption of Shadowheart' which delves deep into her backstory and her journey of self - discovery. It really brings out her complex character.
One interesting Shadowheart fan fiction could be 'Shadowheart's Redemption'. It might explore her character development further, perhaps showing her coming to terms with her past in new and unexpected ways. Another could be 'Shadowheart and the Lost Artifact', where she embarks on a quest for a powerful item, facing various challenges along the way.
First, study Shadowheart's character. Know her backstory, her personality traits, like her being somewhat reserved but also strong - willed. Then, come up with an interesting plot. It could be something related to her past that hasn't been fully explored in the game, for example. Next, write in a style that suits the tone of the game she's from. Keep the language somewhat medieval - ish if that fits.
Well, a smut novel refers to a book where the focus is heavily on sexual themes and often has very detailed and graphic descriptions of sexual acts. It's not for everyone and is usually considered more adult-oriented.
