The people of the Heavenly World had some leeway in preparing for the great war, but it was different for their allies on the inside.
Thalia was surprised to suddenly receive a message from Damien. He had not contacted her since he left the Sacred Abyss last time, and she had become so used to her duties managing the territory that she'd forgotten to wait for him to say something.
So, when that first message came, she was met with some hollow surprise as she wasn't actually that excited to receive it.
However, that feeling only lasted until she saw its content.
"In three days, there will be war. Prepare to rebel against everything you know."
"Ah…"
That was when the surprise came. The Gehenna Tribe never once thought about antagonizing the Dark God. They knew better than anyone that such thoughts would only get them killed.
