In the Battle of the Labyrinth, Percy dreams of Daedalus. In the dream he is with Daedalus and Icharus (his son). The soldiers are coming and Daedalus gives both Percy and Icharus a set of wings. The tells them not to go too close to the sun because the wings use wax to fix them into the frame. Percy wakes up at the point where Icharus has ignored his father's warnings and is falling.
