Some settings feature characters and cultures who typically speak many different languages. If this Setting Rule is in play, your hero knows his cultural or national language plus an additional number of languages equal to half his Smarts die. An elf with a d8 Smarts in a swords & sorcery campaign, for example, knows Elvish and four other languages–perhaps human, dwarven, and two others of her choosing.
