They’re assigned a letter, then sent out into the world. They’re given a choice; to use, or not use, the abnormal skills innate to each of them. They’re called the Littera, and the shadows of the world darken or lighten before their presence.
24 Letters is a D20 Modern campaign set in our world, albeit several years in the future. The PCs explore the political and criminal underbelly of the world as Littera, specialists who are ‘born’ into the world grown and possessing abilities and skill well above those of even the most well-trained operatives.
