You must have at least started chapter 5 of the main quest before this quest line can be accessed. With minimal distractions and limited exploring, the entire quest line will take anywhere from 30-45 mins to complete.
The quest will be highlighted as a blue quest marker with an exclamation point in the middle and is located in the eastern area of Korinthia
(south from Megaris
), in the Isthmus of Poseidon
region - in the Fort Altar of the Cyclops
. The closest viewpoint is the Temple of Apollo (in the Valley of King Lelex, eastern Megaris
or if you haven't synchronized with that one yet; the Temple of Apollo in Korinth, central Korinthia
.The guide portion from this solution is straight from the excellent walk through by Erutaerc and full credit goes to them - I pulled it out of there to make it readily accessible here.Prodigal Son's Return

NOTE: To access this free quest line, I’ll say again that you must have at least started Episode 5 of the main quest and have Update 1.1.4 installed.
