He made it into a game and like any good game, he made rules for it to make it fun. Like the fact that they can only use one annihilator and no transcendents can be involved. He also stopped the demigods from trying to kill each other since this is a joint mission. He didn't specify if they can kill each other after the mission because it wouldn't be fun to watch otherwise. He was particularly looking forward to Helios and Tanya hashing out their rivalry.
It was supposed to be a fun game. The arrival of an army did not change that. Giants of order from 9 churches arrived soon after. They came with an army and waged war on the ant colony. The death of some giants and ants only made the game more fun to watch. Demigods arrived later. The target of the tree father arrived even later. The queen saw him through the eyes of multiple ants.
"The one you asked for has arrived." The ant queen informed the ant plant spirit.
Now we know where the ant queen got divinity and who is helping her. We also know why the royal guards are stronger than normal but are still under the control of the queen.
SWIFTESCAPE was right about the previous question. He listed both available options but he is still right. Tanya and Helios are the only demigods that we are invested in. Now on to the next questions. Why would the tree father target Helios?
