[4] A sequel, Dragon Rider: The Griffin's Feather, was published over a decade later, in 2017,[5] and a feature film adaptation of the same name was released in 2020.

Firedrake travels to the city with his friend Sorrel, a forest brownie with cat features, to find Gilbert Graytail, a rat who specializes in making maps.

The duo meets Ben who provides Sorrel with human clothes so she may go in disguise to find Gilbert while Firedrake stays hidden.

While he rests however, one of the dwarves, Gravelbeard, runs to the castle in that same mountain range, revealing Nettlebrand, the Golden One, a fearsome dragon-like monster whose only purpose in life is to hunt, kill and eat dragons and his servant, Twigleg the Homunculus.

After hearing of the trio, Nettlebrand decides to follow them, hoping to hunt down and kill the last of the dragons because he failed decades before.

Encountering a chicken-like monster known as basilisk and a band of zealous archaeologists, the party eventually befriends a kindly scientist named Professor Greenbloom.

Twigleg relays the news to Nettlebrand, who immediately makes his way to the dig site to find Professor Greenbloom and recover the scales.

The answer to the question appears in two of the Djinn's thousand eyes; it is a path, marked by the Indus River, by a mountain range, and by a monastery.

The Djinn also gives them a prophecy: "When that day comes, twenty fingers will point the way to the Rim of Heaven, and silver will be worth more than gold."

He has grown to be very attached to Ben, and he begins relaying false information to his master, sending him into the middle of a desert where he gets attacked by the sandmen, whom the monster eventually escapes.

Zubeida showed Firedrake not only the tomb of the original Dragon Rider but also a species of flower that collects moonlight in the form of dewdrops on its leaves.

Whilst waiting for the moment of departure, the company discovers Gravelbeard (who was threatened by Nettlebrand into becoming another spy) but fails to catch him.

To Twigleg's dismay, in the center of the Rim of Heaven is a great lake, a perfect gateway for Nettlebrand, who can travel instantaneously by water.

To make sure that he is right, Lola takes Twigleg in her miniature airplane to investigate and distract Nettlebrand, while above the others seeking the Dragons' cave.

He has seen the marvelous gemstones and rock formations in the cave and wishes to enhance them with his skill, revealing that doing so will bring the petrified dragons back to life.

Eager to see their friends again, Ben and Guinevere occupy their time with other investigations of "imaginary" creatures until they can revisit the silver dragons.

The sequel would be set two years following the first book, with Ben living with the Greenblooms at a creature refuge founded in Norway.

[7] The book was published in Germany under the title Drachenreiter: Die Feder eines Greifs on 23 September 2016, with the hopes of releasing it in English the following year in 2017.

[9][10] Funke also announced plans for a third book, tentatively titled The Volcano Adventure, which would be told like a graphic novel, along with mobile phone interaction.
