The Middling Lords

The Middling Lords are part of The Book of Falling by Rob Pegler.

While there are hundreds of vampire clans around the world, the strongest clans in Europe and Russia are those led by the Middling Lords. Considered undead nobility, they have authority over the smaller clans of Europe, and the foreign ones descended from them (their influence doesn’t extend into Asia and Africa, where vampires play by their own ancient rules). They are answerable only to Prince Joseph, reclusive ruler of the vampire world, and act as his representatives. Although allied to one another, they are happy to let the lesser clans fight for position.The actual number of Middling Lords has changed many times over the centuries, but they typically number between nine and twelve.

Though they have yet to appear in the story, the Middling Lords have been mentioned several times. Gabriel Pope encountered them at least once during his early years as a hunter in Europe.
