Key items

Items which allow the player to resolve puzzle, usually triggering the opening of a door or a secret passage.

The Tome of Eternal Darkness, a antediluvian and sinister book, is the most precious and useful of these items, opening narrative 'doors' which lead directly to the following chapters, allowing the characters to use magick, and giving to the main protagonist all the keys for a complete understanding of the plot and secret rules of universe.
