It is actually based quite a bit on Greek mythology. The entire pantheon of gods are represented. As the series begins it is made clear that many Greek stories were never written down, and lost to time. Under that premise it tells a new story, set in the same mythos of the ancient ones. It is well known that Zeus was a philanderer and fathered many illegitimate children. This is just the story of a new one. It stays true to the myths, while creating something wholly new and engaging.
