Descendant of the Chaos Goddess

One day I woke up in a desert full of monsters from Greek mythology.
The last thing I could remember was being told that I was the descendant of the goddess of chaos, Eris.
Now I'm involved with some program to "train" and "nourish" descendants of the gods.
They said that those who do well in the program earn a seat in Olympus next to their godly parent.
Sounds great, but there's just one issue.
I'm related to the weakest god.
