The gods attended the divine council enthusiastically. Apart from the meeting being compulsory, they are eager to attend the meeting because they want to know what he has to say after being silent for so long.
"I call this divine council to order." He said after everyone that will come had arrived.
He informed them of his intention straightaway. "I have decided to end this stalemate with the ants. I have called a Colossus from my church. The Colossus will enter the ant mound and get to the bottom of this issue."
He informed them for several reasons all of which revolves around a single word, "betrayal." A betrayal needs a betrayer. The first reason he is informing them is to let them know of his plan and hopefully reduce the chances of the new god using that as an opportunity to turn gods against him.
