Zernon might be safe for now but he will meet his death in due time. His days are numbered. Legion already has a plan to kill him cleanly without interference. The other gods and archangels. None of them will be able to interfere then.
Helios left the divine plane since he has finished what he came for. He returned to the mortal realm to act as protection for their interests and to conduct experiments. Protecting what they have is very important. Things are going well for them and it needs to be maintained that way. Overconfidence and underestimating the enemy can undo what they have achieved so Legion must be careful and watchful.
Several days later.
The Celestial Supreme gritted his teeth in pain and lamented. "Things are not going well."
