So I was just going through the wiki and noticed that (obviously) children of Athena are scared of spiders and children of Apollo are scared of snakes? Are there any other fears that kind of go toward a whole cabin?
I think any child of the Big Three/Demeter (since Hestia and Hera don't have mortal children) could have a natural fear of Kronos (further than the average demigod) or any kind of monster that could eat them
