Type of pet: Dalmatian dog
Character who owns pet: Aria Sinclair
Why the character has this pet: Grace was Aria's fifth birthday gift, and she was the one who guided Aria to Camp Half-Blood, via directions from the school satyr. Aria and grace are very close, and Grace protects Aria as best she can.
Special Abilities: Grace will be alive as long as Aria needs her, and she has celestial-bronze teeth. (it came with the blessing she received that made her alive as long as she was needed. To be needed in this context, she needs to be able to protect aria.)
Side note: Grace is a very friendly dog and she lives with Aria in the cabin.
