The Argo II has been relentlessly attacked for two days by rock gods called numina montanum in Latin (or ourae in Greek). Leo Valdez defends the ship by firing celestial bronze canons at them. Once his attacks fail, they fly away from the Apennine Mountains. Leo wants to wake Frank Zhang, Piper McLean, and Jason up, but Hazel vetoes his idea because barely any of them have been able to sleep due to the attacks. Hazel blames the attacks on the fact that earth spirits do not like children of Hades/Pluto, as they are children of the Underworld. The trio throw around suggestions on how to get over the mountains. Hazel prays to her dad to give her a sign of help and in the distance she spots Arion. Hazel then tells Leo to get close enough to the ground where she can talk to Arion.
