[Percy Jackson] Why didn't any other pantheons interfere when Kronos invaded NYC? Surely Kronos destroying the Olympians wouldn't be great for any of the other pantheons

Same with Apophis. He was trying to destroy the world, and yet only the Egyptian pantheon was fighting him. Shouldn't the other pantheons have a vested interest in stopping him too, since they are also part of the same world?

There are rules.   It seems pantheons can’t really interfere with each other. 

In addition, they probably knew they didn’t need to.    They likely knew the romans were playing their part. 


After all, they are more or less playing their parts, not agents of free will.     At least, that’s how the books come across to me.
