Bards are a hidden character added in the [[Hellfire]] expansion, only playable once they've been enabled by the [[Command.txt]] file. As an unfinished character, the Bard uses the rogue's graphics, though the two classes play considerably differently.
Like the Barbarian, the Bard is a hidden character and is thus deprived of even the sparse game fiction Sierra bestowed upon the Monk. Invent your own story for the character, and enjoy the dual wielding preview she provides.
