Leaving weaknesses in his own creations so he can use it against anyone that wields them against him... big brain. I hope you try and put a new spin in how old stories involving him are and maybe creating some new non canon lore.
I'm very confused about this novel tbh, Why did you decide Hephaestus be the last olympian? I'm sure you realize dinoysus was the last accepted olympian...? Was it for some plot device or whatever?
I have one problem with this it feels like it needs 2 chapters daily or longer chapters for the wait. The other parts are great 4 out of 4 as I only do 5 for things I would pay for.
