A sorceress of great power, Lumi, better known as the Snow Queen, is the commander of the Emperor's personal guard. Once naive and good-natured, with a childlike and somewhat gullible personality, Lumi had a long relationship with Jack Horner. Trusting him, she gave him her powers for a while while she was unwell, creating the persona of Jack Frost. Subsequently, however, she matured, showing a sharp mind and a cunning aptitude. Tall and quite beautiful, she is generally surrounded by an aura of cold, to the extent that it's usually snowing in her vicinity, often to the annoyance of those around her, not that any of them would dare say anything. She is capable of pulling in the winter weather surrounding her if she so chooses, but rarely does so. She was present when Boy Blue cut off the head of the Emperor and even detected his presence before he revealed himself, but was unable to determine who he was masquerading as and thus prevent his attack. She seems to have either always known who the true leader of the Empire was or has known for quite some time, she has been repeatedly shown as one of Geppetto's closest and most trusted allies. When Blue escaped from captivity, Geppetto swore to send the Snow Queen after him to get revenge. She acted as host of the Imperial conference called after Bigby's destruction of the magic grove. She commands legions of frost creatures, including giants. At the conference, she set out a four-stage plan for the invasion and destruction of the mundane world, which she calls "the four plagues". First, thousands of warlocks will release six deadly diseases; secondly, dragons and fire imps will burn the world's cities; third, the Snow Queen's minions will turn the world to perpetual winter; finally, with all crops and means of production destroyed, the remaining humans will starve to death. The Empire can then use the mundane world as a prison. As a result of Pinocchio's briefing, Lumi has been ordered to amend the plans to ensure that all the Fables living in the mundane world have been assassinated prior to any attack, to prevent them rallying the technologically advanced mundane forces against the Empire.
