Man with the rosette

The man with the rosette was one of the four surviving elementals who survived the destruction of Gallifrey.

Biography
The man with the rosette knew the Doctor before he had lost his memories. The man was known to have tried to destroy the universe while the Doctor tried to save it. The man and the Doctor "had all of time and space as [their] battlefield", and had many duels upon it. (PROSE: The Adventuress of Henrietta Street)

During the War in Heaven, Mother and Father were shown a vision by a loa where, in the post-War future, the Magistrate toyed absently with his rosette while he and the other Ministers waited for their Elemental Emperor who wandered aimlessly in an "exile's century". (PROSE: The Story So Far...)

After the destruction of Gallifrey, the man travelled to Earth in the 18th century and sat with Scarlette in a pub during a brawl. He wore a blue Whig rosette and spoke with her about politics. He left before the Eighth Doctor arrived.

He later met Scarlette at the London docks, where he gave her a pair of rings for the Doctor's wedding. At the Doctor's wedding he sat in the seat reserved for the Doctor's family. He did not interact with the other guests but simply sat quietly and helped himself to the wine.

The man left a wedding present for Scarlette: a fake rose of blue and white satin, resembling no flower on Earth.

The man later met the Doctor in the Kingdom of Beasts. As they stood on a hill, they talked about the state of the universe without Gallifrey in it. The man told the Doctor that he would not fight him because there were only four of their kind left in existence. He told the Doctor that Sabbath and his people were now the future of the universe before he quietly left.

The man was present at the fall of the house on Henrietta Street, where he told Lisa-Beth that he was leaving and that, if he couldn't find something to alleviate his boredom, he would go to sleep until the universe was ready for him again, even if it took a million years. He then walked away from the house on Henrietta Street.

Over the next centuries, many individuals impersonating the Doctor claimed that the man had returned in an "unexpected capacity". However, the meaning of this was never revealed. (PROSE: The Adventuress of Henrietta Street)

In a vision of the four surviving elementals, the Eighth Doctor and Marnal saw the man wearing his blue rosette. (PROSE: The Gallifrey Chronicles)

The man and the other elementals died sometime during the Emperor's rule, the Emperor having outlived them all. (PROSE: Father Time)

Appearance
The man with the rosette had dark hair and spoke with an English accent. He was noted to be slim and of "distinguished middle age". He wore a black shirt upon which he sported a blue and white rosette, signifying the colours of the Whig party. While the Eighth Doctor had a bear, the man was cleanshaven; (PROSE: The Adventuress of Henrietta Street) after the Doctor shaved, the man grew a pointed black beard. He had a sallow face. His appearance (PROSE: The Gallifrey Chronicles) matched that of the Magistrate in an alternate timeline. (PROSE: The Infinity Doctors)
