Status Updates From Stolen Spring

Percy's big, horrible secret is that she likes porn. I'm going to drive off a cliff.

How was the decision to make the names vary a thing? Demeter keeps her name but Zues and Hades become Dimitri and Damon. Aries is Boreas (and is Russian.) Meg exists but not Minthe. Cerberus is Cerbie and is an ancient, dying dog. Like I don't understand any of the world building (because it doesn't exist) or the character decisions.
