An allusion is essentially when an author makes some kind of reference to something that isn't really "part" of the text. By this I mean that the author is referencing to something historical or literature. Like in this sentence the author references Hercules. Hercules is from mythology. A easier way to think about this is linking it to real life. A lot of times teenagers "quote" or reference their favorite songs/TV shows/ movies/books in daily conversation. In this situation the teenager is making an allusion.
The moral of the story is to not be greedy, King Pluto got his wish but at what cost. The greed clouded his judgment and it lead to the death of his daughter.
