Thalia Grace
Thalia and the hunters were close by when Apollo signaled for back up. They arrived with Leo and Festus to aid in the rescue operation and she decided to rode on Livia with Apollo, so she could help them to escape. After they fled, the lieutenant of Artemis offered the fallen god Moonwater to regain his strength. Then she finally says Artemis was forbidden by Zeus from interfering with Apollo but still ordered the Hunters to help him. They three then head back to the Waystation.
