List of characters in the Camp Half-Blood series
Grover Underwood is a satyr and Percy Jackson's best friend. He has found the four most powerful Greek demigods of the century: Percy Jackson (son of Poseidon), Thalia Grace (daughter of Zeus), and Nico and Bianca di Angelo (children of Hades). Before his death, Pan (the god of nature) says Grover is the bravest satyr ever to be. He names Grover as his successor to carry on his word to protect the wilderness. The Council of Cloven Elders is angered by this choice. He is the boyfriend of the tree nymph Juniper. But in The Last Olympian he is chosen as a replacement for Leneus (another Satyr who died in battle) on The Council of Cloven Elders after.
