Lumi the Snow Queen

A sorceress of great power, Lumi, better known as the Snow Queen, is the commander of the Emperor's personal guard. She is one of four sisters, each representing one of the seasons, who jointly ruled four kingdoms with each moving in a yearly cycle to bring the seasons in a predictable manner to their subjects.

She was once naive and good-natured, with a childlike and somewhat gullible personality. That changed after Lumi had a relationship with Jack Horner. Feeling unwell as the seasonal change approached, she naively gave her powers to Jack, creating the persona of Jack Frost, trusting him to transfer the winter season to the next kingdom in the cycle. Jack immediately ignored her wishes, seeking new women to seduce and generally misuse the abilities given to him, abandoning Lumi, who quickly realised she was not, in fact, unwell, but was pregnant with Jack's child. Jack's misadventures disrupted the flow of the seasons, turning the population against her. Eventually, Lumi's three sisters persuaded Jack to return the powers that he'd taken. Angered by his betrayal, Lumi grew as cold as the season she controlled.

The Snow Queen has repeatedly shown 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 commands legions of frost creatures, including giants. She seems to have either always known who the true leader of the Empire was or has known for quite some time, as she has been repeatedly shown as one of the Adversary's closest and most trusted allies.
