London whispers of two great powers operating in the shadows: * The Lord of Crime, William James Moriarty, who seeks to destroy the corrupt class system. * Sherlock Holmes, the consulting detective who uncovers the truth behind every mystery. But neither realizes a third force has emerged. Y/N leads an independent faction known as The Lantern Society, a network dedicated to helping both nobles and commoners escape abusive situations, relocate, and start new lives. Using information gathered from every level of society, Y/N secretly works with both Moriarty and Sherlock while remaining loyal to neither. The balance shatters when Charles Augustus Milverton discovers secrets that could destroy all three.
