Lord Womble

Lord Womble is a courtier to Queen Albia of England. He is also a unicorn (but standing upright).

He first appears in a large anteroom to Albia's garden, where he meets Agatha and Zeetha to conduct them to, as it turns out, a garden containing a very tall Albia, some very small people, and a lion. His first words are a slightly snarky reply to Agatha's overheard comment to Zeetha that she's not like her ancestors, but immediately after that he very politely addresses the two women by their titles and invites them to follow him for their audience with the Queen.

Possibly relevant outside information
In heraldry, the unicorn often refers to Scotland. Queen Victoria had a notoriously informal Scottish attendant named John Brown, who was known for saying things that should never be said. The film Mrs. Brown (1997, directed by John Madden) is a dramatization of their lives. (The lion similarly refers to England.)
