The Prime Minister's cavalry are an elite squad of elf soldiers that serve and protect the Elf Prime Minister. They appear in the animated series ("Chapter 1: The Hidden People"), the graphic novels ("Hilda and the Midnight Giant"), and the Tie-In books ("Hilda and the Hidden People").
They ride on rabbits and are armed with slings, which they use to throw rocks at their enemies.
- In "Hilda and the Hidden People", Alfur refers to the cavalry as "The Light Brigade". This name is not used in the graphic novel or animated series.
