Who is Festus?

Festus is a mechanical dragon made by a Hephaestus camper long ago and restored by Beckindorf. When Beckindorf died it went haywire and started attacking the camp. Leo finds it and fixes it, naming the dragon Festus and giving it wings. They use Festus as flying transport on their quest, but the dragon is destroyed when they are shot down at Midas' estate. Leo saves Festus' head, planning to use it as a masthead on the flying ship that he will build one day.
