Gods shouldn't be marked through vessels. That's the norm. They also shouldn't be harmed through vessels either but they really thought that scythe was going to cut them at that time. They shouldn't be scared to death through vessels too but their instincts screamed out danger. There are a lot of things that shouldn't have happened but here they are with the mark of a scythe on their Godhood.
The real reason why Stelios' vessel was the last to die is that he chose to resist the mark of death. The attack was supposed to mark him and then destroy the vessel but as a Celestial, he noticed the hidden danger. The word DEATH wasn't a simple word, it was backed with Authority so it needed Authority to resist which the other gods are lacking in. The ignorant fools didn't even know that they had been marked.
"What do we do now?" Harkam asked in desperation.
