The realm lord doesn't seem to be worried about the era of conquest but there is someone here that is very worried about it. Nothing the realm lord says will prevent mother high heaven from not worrying. She has to worry now that some random world god is even warning them to be prepared. She thought she was being paranoid before but it seems she has underestimated the trouble that is coming for them when the era of conquest begins.
The world god watched them go dragging the continent away. He saw how the realm lord gained control of it and it increased his longing for Authority. Unfortunately, he can't get it easily. Even this deal is just for an opportunity to get it. Getting it will depend on his efforts but there is a possibility of getting it where there was none before.
