The Origin Gods had been waiting for that moment. They weren't sure if Shiba end Eini were killed or not, but they weren't too important when compared to Ravier.
Aknarel also noticed that Ravier was there.
Before, he sensed an aura that belonged to the Fake Origin path that he gave his son, but it was obvious that the one using it was someone else, so he guessed that something big was going on, which made him pay utmost attention.
Thus, he was able to sense Ravier's aura as soon as he appeared.
"Run! They can't kill me right now! This is a trap!"
Aknarel concentrated in order to be able to send that Divine Sense message. He didn't know the plans of the other Origin Gods, but he didn't believe they hadn't prepared anything for that situation.
Given that Shiba and Eini weren't there anymore and that Ravier confirmed by himself that he was there, Aknarel believed that Ravier should just go back to bring back reinforcements.
