Griffin falls to the underground after accidentally dropping a fiery stick on his friend Luna. Finding out that dead bats live here forgetting that they died, he finds multiple bats with a strange glow. In the underworld, Cama Zotz orders the revived Goth to hunt down Griffin. After Frieda gives the sound map to Griffin, he and Luna attempt to escape from the underworld, and are helped by other dead bats that know each other. Goth kills Griffin, but Shade gives up his life for Griffin and Luna, who return to the upper world. Main characters Shade: A silver-haired bat who is teased about his lack of size and strength. He learns about Cassiel from the colony. He is naïve to the dangerous world around him, where owls rule the skies and he dares look at the sun - which in their world is forbidden - without much idea about the consequences. This starts off a chain of events, which test both his loyalty and strength to the fellow bats. He is the main protagonist of the series who saves his colony more than once and slowly rises in the ranks to become the respected Silverwing he always wanted to be. In 'Firewing', he is a father and appears briefly in the main plot. Marina Brightwing: An Eastern red bat and Shade's closest friend who is one year older than him. After being banded, she was banished from her colony and went to live on an island. In Silverwing after meeting Shade at the island, she escorts him to reunite with his colony. Goth tore off Marina's band. In Sunwing, Shade and Marina become mates. In Firewing, Marina's role is much more minor compared to the other two books in the series; she briefly appears in the beginning and is only mentioned in the ending. This was probably to give Griffin, their son, more character growth and development. Goth: A cannibal bat and prince of the Vampyrum spectrum who is deceptive and cunning. He and Throbb were taken from South America to the city. His carnivorous nature makes him eat many kinds of animals, including birds, turning the owls against bats. In the first book, Goth and Throbb are captured by scientists. They escape, meet Shade and Marina, and plot to follow them to Hibernaculum, where they could kill the entire colony. In the end, Goth is injured by lightning.
