Well we all know that Leo,Piper and Jason but who are the others here is what I think
The Roman demigods should be Bobby hazel reyna(is that how you spell her name)but I think the seventh demigod schould be a daughter of Nyx the goddess on night
Reason
Cause she wil be really powerful and that she might be able to make Gaia go back to sleep and defeat the giants
So what do you think? Leave a comment
