October Novel Prep Challenge

I am struggling so bad today to get my head around this assignment! I've tried to break down the different races with snowflakes and I've tried to just what if to narrow things down but my head is going to explode! What are commonly thought things about Harpies, Sirens and centaurs? I cant do research on my work computer and my phone is hard to read! (I have a lot of downtime today and figured it would be productive to write) Seriously frustrated right now.

I'll just keep plugging in little details and hope they help form the whole picture at some point!
