If you’ve never seen Thalia run into battle, you have never been truly frightened. She uses a huge spear that expands from this collapsible Mace canister she carries in her pocket, but that’s not the scary part. Her shield is modeled after one her dad Zeus uses – also called Aegis – a gift from Athena. The shield has the head of the gorgon Medusa molded into the bronze, and even though it won’t turn you to stone, it’s so horrible, most people will panic and run at the sight of it.
