Grover, Percy and Annabeth discuss Thalia, in "We Visit the Garden Gnome Emporium"

Thalia Grace is a Greek demigod and the daughter of Zeus. After she was mortally wounded by attacking monsters, she was transformed into a pine tree on Half-Blood Hill, which still stands as the official border for Camp Half-Blood to this day.

History[]

Due to being born against the Pact of the Big Three decreeing that the Big Three can't have any more demigod children, Thalia was targeted by monsters. Grover Underwood attempted to lead Thalia, Annabeth Chase and Luke Castellan to Camp Half-Blood, but they were chased by the Furies, including Alecto. Refusing Grover's attempts to dissuade her, Thalia bravely made a stand to protect her friends and fell to the Furies. Mortally wounded and dying, Thalia was transformed into a pine tree by Zeus in order to preserve her spirit. Thalia's tree put up a magical border around camp, protecting all demigods living within from monster attacks.

"We Visit the Garden Gnome Emporium"[]

Before leaving on the Quest for the Master Bolt, Annabeth stops to say goodbye to Thalia's Pine Tree which Percy Jackson notices. Grover explains how Thalia, Annabeth and Luke were chased to Camp Half-Blood by the Furies and Thalia, ignoring Grover's attempts to dissuade her, had made a stand to protect her friends and was turned into a tree by Zeus in order to preserve her. Percy cynically comments on how the only thing that the most powerful being in the universe could think of to save his daughter was to transform her into a tree, quipping that Thalia had "met a pinecone's fate." Annabeth warns Percy that forbidden children are always in danger, even the most powerful ones like Thalia was.
